I have source code of a compiler which I am building like this:
/path/to/srcdir/configure --prefix=/path/to/installdir
make
make install
I want to distribute the resulting 'installdir' to other machines, with the intent that anybody could use the compiler binaries without going through the 3-stage build process (I am just including the installdir in my distribution tarball).
For testing, I am copying the installdir to another machine under a different user, and then just trying to compile a test program using the binaries I just copied over, like this:
installdir/bin/ucc -mp -o test load_bl.c
Then, I get an error as follows:
cc1: error: /home/sghosh/normalbuild/installdir/open64-gcc-4.2.0/include: Permission denied
cc1: error: /home/sghosh/normalbuild/installdir/open64-gcc-4.2.0/lib/gcc/x86_64-redhat-linux/4.2.0/include: Permission denied
cc1: error: /home/sghosh/normalbuild/installdir/open64-gcc-4.2.0/x86_64-redhat-linux/include: Permission denied
The /home/sghosh/normalbuild/install is what is specified as --prefix during configure on my build machine. The installdir/bin/ucc binary require some files in the open64-gcc-4.2.0 dir under installdir, but since that is the path mentioned in --prefix, so it's still looking for it there, and I want it to look into the same dir in the current machine. FYI, I do not have sudo/root privileges.
How do I come up with a binary distribution that would work in any machine (build once, use anywhere sorts), and not look into the initial --prefix path in this case?
I have had a similar question in superuser, but since lots of edit happened and I got no response to the new question, so I am writing it here.

I am using my own laptop locally with win 10 system and intel parallel studio .
After I compiled my mpi code with mpiifort and run it with mpiexec for the first time. It warns me to input account and password, like below
I am sure I put in the correct password. But it just didn't work. What does "execvp error" mean? I never encountered this problem before on my old win8 system. I just installed this new win10 system on my laptop, everything is new. Could somebody please help me instead of making close vote without any comment? At least, say something
execvp error on file is the error from doing execvp system call. It is variant of exec system call used to start programs. In your case the mpiexec program tries to start the mpi-learning-pack.exe file on the target hosts (according to settings, probably some environment settings). This error says that it can't start your program on target hosts, because either it is not executable file, or cannot be found (not copied to target hosts or have no full path).
mpiexec does not copy file to targets, you should copy it to every target hosts.
You can also check if it executable by manually starting it on target host: just login to target host and type mpi-learning-pack.exe without mpiexec;
program may not start if there are no any of required library on target.
Or your account has no enough privileges like https://software.intel.com/en-us/forums/intel-clusters-and-hpc-technology/topic/607844 https://software.intel.com/en-us/forums/intel-clusters-and-hpc-technology/topic/624054
Or you just should use relative (mpiexec [options] .\mpi-learning-pack.exe) or full path (mpiexec [options] e:\w\work\fortran\_test_and_learning\mpi-learning-pack.exe) of target executable like in https://software.intel.com/en-us/forums/intel-clusters-and-hpc-technology/topic/624054
I followed the Software Collections Quick Start and I now have Python 3.5 installed. How can I make it always enabled in my ~/.bashrc, so that I do not have to enable it manually with scl enable rh-python35 bash?
Use the scl_source feature.
Create a new file in /etc/profile.d/ to enable your collection automatically on start up:
$ cat /etc/profile.d/enablepython35.sh
#!/bin/bash
source scl_source enable python35
See How can I make a Red Hat Software Collection persist after a reboot/logout? for background and details.
This answer would be helpful to those who have limited auth access on the server.
I had a similar problem for python3.5 in HostGator's shared hosting. Python3.5 had to be enabled every single damn time after login. Here are my 10 steps for the resolution:
Enable the python through scl script python_enable_3.5 or scl enable rh-python35 bash.
Verify that it's enabled by executing python3.5 --version. This should give you your python version.
Execute which python3.5 to get its path. In my case, it was /opt/rh/rh-python35/root/usr/bin/python3.5. You can use this path to get the version again (just to verify that this path is working for you.)
Awesome, now please exit out of the current shell of scl.
Now, lets get the version again through this complete python3.5 path /opt/rh/rh-python35/root/usr/bin/python3.5 --version.
It won't give you the version but an error. In my case, it was
/opt/rh/rh-python35/root/usr/bin/python3.5: error while loading shared libraries: libpython3.5m.so.rh-python35-1.0: cannot open shared object file: No such file or directory
As mentioned in Tamas' answer, we gotta find that so file. locate doesn't work in shared hosting and you can't install that too.
Use the following command to find where that file is located:
find /opt/rh/rh-python35 -name "libpython3.5m.so.rh-python35-1.0"
Above command would print the complete path (second line) of the file once located. In my case, output was
find: `/opt/rh/rh-python35/root/root': Permission denied
/opt/rh/rh-python35/root/usr/lib64/libpython3.5m.so.rh-python35-1.0
Here is the complete command for the python3.5 to work in such shared hosting which would give the version,
LD_LIBRARY_PATH=/opt/rh/rh-python35/root/usr/lib64 /opt/rh/rh-python35/root/usr/bin/python3.5 --version
Finally, for shorthand, append the following alias in your ~/.bashrc
alias python351='LD_LIBRARY_PATH=/opt/rh/rh-python35/root/usr/lib64 /opt/rh/rh-python35/root/usr/bin/python3.5'
For verification, reload the .bashrc by source ~/.bashrc and execute python351 --version.
Well, there you go, now whenever you login again, you have got python351 to welcome you.
This is not just limited to python3.5, but can be helpful in case of other scl installed softwares.
I am attempting to install CouchDB on my planetlab Unix machines from the source packages.
I installed Erlang r16b01 using Kerl: http://docs.basho.com/riak/1.3.0/tutorials/installation/Installing-Erlang/#Install-using-kerl
I installed openssl from the source package.
So, I ran "./configure --with-erlang=path/to/erlang/using/kerl" and I get the error
"configure: error: Could not find the Erlang crypto library"
This error indicates that Erlang was not compiled with OpenSSL support.
So, I tried using
"KERL_CONFIGURE_OPTIONS=--with-ssl=path/to/openssl/lib"
(Not sure if I'm using the above command correctly)
Then, reinstalled and reactivated Erlang.
This still brings up the same error.
I checked if Erlang if it could execute "crypto.start()", and it let me type the command, but it doesn't have a reply "ok" like in the documention: http://dennisreimann.de/blog/installing-couchdb-and-erlang-on-ubuntu-hardy/
Please help!
1) Did you first create a user couchdb and then do everything as that user? Including erlang build and install? That might be easier.
2) There is an error in your test, you need to terminate your command in the erl shell with a dot, otherwise you get no responce, like you already noticed. crypto:start(). is correct:
$ erl
Eshell V6.1 (abort with ^G)
1> crypto:start().
** exception error: undefined function crypto:start/0
After a successful build and installation it will respond ok:
$ erl
Eshell V6.1 (abort with ^G)
1> crypto:start().
ok
And you can also stop it afterwards:
2> crypto:stop().
ok
3>
=INFO REPORT==== 10-Aug-2014::20:22:06 ===

type: temporary
3) You need the development package of OpenSSL including the header files as well as the binary command program openssl. At least version 0.9.8 of OpenSSL is required. As a sidenote for people who are on debian and ubuntu, it is usually enough to run:
sudo apt-get install openssl libssl-dev
In your case, you should somehow make sure that your openssl source install includes all the above (openssl binaries, header files).
4) Most probably it could be an issue with finding the libraries. I recommend reading this answer, which deals with a unix based system, and it could point you to the right direction:
https://stackoverflow.com/a/14776521/362951
Depending on the error message after the crypto:start(). you could try to somehow add the path and logout of the shell and relogin and then activate kerl and try again. No need to rebuild if it was present and found at compile time.
5) Your kerl configuration looks good. Again using debian/ubuntu paths a ~/.kerlrc could look like
KERL_CONFIGURE_OPTIONS="--with-ssl=/usr/lib/ssl"
And hopefully the ssl path you are inserting is the correct one.
You could also try and omit the path, maybe it finds the correct one by itself. On http://www.erlang.org/doc/installation_guide/INSTALL.html it looks like it is valid to do so:
KERL_CONFIGURE_OPTIONS="--with-ssl"
Currently kerl silently produces a build without crypto if it fails to find the headers https://github.com/yrashk/kerl/issues/31
6) I see you are giving the --with-erlang parameter to couchdb, does it point to the right directory? Or maybe it needs to go one level deeper or one level up.
Otherwise possibly an older, system. wide erlang could be used, if found.
Also I am not sure if the combination of a kerl environment and passing the erlang location using the --with-erlang parameter to couchdb works. I did not try the --with-erlang parameter with kerl, because I activate the kerl environment before compiling couchdb and then again before the couchdb start script.
So I am trying to install a program on my windows machine that required me to install Cygwin to install it. So I am working from a README file and assueme I have compiled the code previously correctly (its one line sh build.sh) and when actually trying to use the program I get the following error:
BabakP#Babak /cygdrive/c/Users/BabakP/Desktop/test
$ ./Runlock input.tst output.tst 1
./Ostrich: Exec format error. Binary file not executable.
I guess I am trying to figure out why I am getting this error so any suggestions on how to troubleshoot it would be great!
./Ostrich is a Mac executable. It can't be executed under Cygwin. (A MacOS emulator that runs under Windows or Cygwin is theoretically possible, but I don't know of any such thing.)
Without knowing the details of the software you're trying to install, it's hard to say how or whether you can fix it.
You may be able to rebuild Ostrich from source (if you have the source, and if it's not MacOS-specfic).
I am using SQLite 3 for Database management in my ARM9 based microprocessor.
I want to cross compile the latest version of the SQLite 3 for my project in Linux (Ubuntu 10.04). I am using the arm-none-linux-gnueabi-gcc compiler for development.
I tried to cross compile using following commands,
Downloaded the sqlite-amalgamation-3.7.0.tar
I extract it and then write the following command on Terminal,
sudo ./configure --exec-prefix=/media/8CCC8E9BCC8E7F68/SQLIte3/sqliteinstall/ --host=arm --target=arm CC=/opt/arm-2011.03/bin/arm-none-linux-gnueabi-gcc AR=/opt/arm-2011.03/bin/arm-none-linux-gnueabi-ar STRIP=/opt/arm-2011.03/bin/arm-none-linux-gnueabi-strip RANLIB=/opt/arm-2011.03/bin/arm-none-linux-gnueabi-ranlib CFLAGS="-Os"
It successfully cross compiled the SQLite.
Then,
sudo make command.
It successfully run.
Now "make install " command.
It did not give me an error but when i went to the config.log file i found there is some sentences as following,
1.conftest.c:17:7: error: size of array 'off_t_is_large' is negative
2.conftest.c:12:28: fatal error: ac_nonexistent.h: No such file or directory
compilation terminated.
3.conftest.cpp:23:28: error: ac_nonexistent.h: No such file or directory
4.conftest.c:67:13: error: invalid type argument of unary '*' (have 'int')
I doubt that weather it has been cross compiled properly or not.
I can not understand.
I inserted the library on my board it works fine but the problem is that the speed got very slow. I think there is some problem that i have not set any flags for the GCC compiler.
I could not find any options.How I can set the particular flags for the GCC compiler so that unnecessary features can be omitted.
You probably shouldn't try to do cross-compilation manually. Instead, use an embedded Linux build system that will do that for you, and automate the cross-compilation process entirely. My favourite is of course Buildroot (http://buildroot.org), but there are plenty of others (with varying levels of quality, complexity and features) : OpenEmbedded, Yocto, PTXdist, etc.
