Why are there undefined references to PPP_GetInterface, PPP_ShutdownModule, and PPP_InitializeModule - google-nativeclient

I am trying compile a pexe file using the portable native client. I am following the instructions at this page:
https://developer.chrome.com/native-client/devguide/devcycle/building
I am trying to build a pexe and link it with a static lib as shown on the page. My command line is as follows.
/home/adev/opt/nacl_sdk/pepper_37/toolchain/linux_pnacl/bin/pnacl-clang++ -o pim-pnacl.pexe pim-pnacl.o -L/home/adev/opt/nacl_sdk/pepper_37/lib/pnacl/Release -lppapi_cpp -lppapi -L../libpidec -lpidec
and I get the following errors.
/home/adev/opt/nacl_sdk/pepper_37/toolchain/linux_pnacl/sdk/lib/libppapi_stub.a: error: undefined reference to 'PPP_GetInterface'
/home/adev/opt/nacl_sdk/pepper_37/toolchain/linux_pnacl/sdk/lib/libppapi_stub.a: error: undefined reference to 'PPP_ShutdownModule'
/home/adev/opt/nacl_sdk/pepper_37/toolchain/linux_pnacl/sdk/lib/libppapi_stub.a: error: undefined reference to 'PPP_InitializeModule'


For the record, the problem was in the pim-pnacl.o it needed to be compiled with the -c flag. This is the correct way to compile a single .o file:
/home/adev/opt/nacl_sdk/pepper_37/toolchain/linux_pnacl/bin/pnacl-clang++ -o pim-pnacl.o pim-pnacl.cc -O2 -I/home/adev/opt/nacl_sdk/pepper_37/include -c
I had omitted the -c and this caused linker problems.

How to compile sqlite3 extension - CSV virtual table

I am trying to use the CSV Virtual Table extension for sqlite3. I get stuck on the first step of compiling the extension on a Mac (MacOS High Sierra 10.13.6).
I downloaded the source code for csv.c from this page. I also grabbed the sqlite source code amalgamation from here.
I used the following command to compile:
gcc -g -fPIC -dynamiclib csv.c -o csv.dylib
However, I get the following error:

What am I doing wrong?

Richard Hipp at sqlite.org posted a solution on how to compile an SQLite extension.
The script for compiling the CSV extension looks like this (based on https://www.sqlite.org/loadext.html and https://github.com/sqlite/sqlite/blob/master/README.md):
wget https://www.sqlite.org/src/tarball/sqlite.tar.gz
tar xzf sqlite.tar.gz
mkdir bld
cd bld
../sqlite/configure
make
gcc -g -I. -fPIC -dynamiclib ../sqlite/ext/misc/csv.c -o csv.dylib
Testing the script:
echo -e 'col_text,col_int\napples,3\noranges,5' > sample.csv
./sqlite3 '' '.load csv' 'CREATE VIRTUAL TABLE temp.t1 USING csv(filename="sample.csv");' 'SELECT * FROM t1;'
That's it.
You can also try compiling csv.c with an existing sqlite3 installation. For sqlite3 installed with Homebrew, it would be:
curl -O https://raw.githubusercontent.com/sqlite/sqlite/master/ext/misc/csv.c
gcc -g -I/usr/local/opt/sqlite/include -fPIC -dynamiclib csv.c -o csv.dylib
/usr/local/opt/sqlite/bin/sqlite3 '' '.load csv'
The last line is testing the newly compiled library in the Homebrew sqlite3. The default $ sqlite3 comes from the MacOS bundle and is outdated sometimes.

I managed to find a workaround and use an Ubuntu docker container, where I was able to successfully compile and use the extension. Here are the steps I followed:
docker run -ti --rm -v $(pwd):/host ubuntu bash
# Steps to build SQLite and CSV Virtual Table extension from source inside an Ubuntu docker container
cd /host
apt update
apt install -y vim build-essential zip wget
wget https://sqlite.org/2020/sqlite-autoconf-3310100.tar.gz
tar xvf sqlite-autoconf-3310100.tar.gz
cd sqlite-autoconf-3310100
./configure
make
./sqlite3
# Obtain csv.c and change <sqlite3ext.h> to "sqlite3ext.h" in the file
vi csv.c
gcc -g -fPIC -shared csv.c -o csv.so
./sqlite3
#sqlite> .load ./csv
#sqlite> CREATE VIRTUAL TABLE temp.t1 USING csv(filename='/host/users.csv',header);
#sqlite> .headers on
#sqlite> SELECT * FROM t1 LIMIT 1;
You can use a similar process to build for a Lambda function (CentOS). See this github repo for more details.
I still haven't figured out how to get it to compile directly on Mac, so any help would be greatly appreciated!

Leveraging off of Anton's answer for an Ubuntu-like distro, the following is mostly workable:
wget https://www.sqlite.org/src/tarball/sqlite.tar.gz
tar xzf sqlite.tar.gz
mkdir bld
cd bld
../sqlite/configure
make
A gotchas in getting this far:
You may need to do this:
sudo apt-get install tcl8.6-dev
It will complain about not having access to tcl. If that's the case, you need to install and go back to the configure step.
Now, make should work unless you have other missing dependencies.
Assuming that works, now for the gcc:
gcc -I. -fPIC -shared ../sqlite/ext/misc/csv.c -o csv.so -lm
Now it's time to run. You need to set LD_LIBRARY_PATH. Assuming you are still in the bld directory:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:`pwd`
or substitute the `pwd` for your full path to the csv.so file.
NOW! Now, you can run it. Enjoy.

trouble compiling chrome native client tutorial

I tried following the tutorial here for NaCl or PNaCl or native client or pinnacle whatever the name of the day is and got this:
F:/nacl_sdk/pepper_31/toolchain/win_x86_newlib/bin/i686-nacl-g++ -o hello_tutori

collect2: ld returned 1 exit status
Makefile:64: recipe for target 'hello_tutorial_x86_32.nexe' failed
make: * [hello_tutorial_x86_32.nexe] Error 1
Any ideas?

It looks like you are running the old "hello_tutorial" example with the new pepper_31 SDK. Please use this new documentation instead:
https://developers.google.com/native-client/dev/devguide/tutorial/tutorial-part1
This source for this tutorial can be found in the pepper_31 SDK in the directory pepper_31\getting_started\part1.

The new tutorial cited by binji is set up to build/run a pexe. To use nexe's as in the older example, update the tutorial's Makefile:
Add LDFLAGS for each target:
LDFLAGS_NEWLIB_ARM := -L$(NACL_SDK_ROOT)/lib/newlib_arm/Release -lppapi_cpp -lppapi
LDFLAGS_NEWLIB_X86_32 := -L$(NACL_SDK_ROOT)/lib/newlib_x86_32/Release -lppapi_cpp -lppapi
LDFLAGS_NEWLIB_X86_64 := -L$(NACL_SDK_ROOT)/lib/newlib_x86_64/Release -lppapi_cpp -lppapi
and change the $(LDFLAGS) specified for linking the respective targets.

How to build Quazip 0.5.1 on Windows 7?

I'm trying to build the quazip libary (version 0.5.1) on Windows 7 (32-bit) with Qt 5.0.1 32-Bit LGPL installed.

But in my Zlib-Folder (C:\Qt\Qt5\5.0.1\Src\qtbase\src\3rdparty\zlib) are all this listed files installed.
.
As I tried to solve the problem, I have added into the quazip.pro and into the quazip.pri:
INCLUDEPATH += $$[QT_INSTALL_PREFIX]/src/3rdparty/zlib
, how it is suggested here.
All other solutiuons I have found on Google so far aren't helping.
I hope someone of you can help me.
Greetings,
LVreg

The problem is that QuaZIP can not find the zlib library. You should include the path of the headers an also the libraries when you run qmake:
qmake "INCLUDEPATH+=C:/Qt/Qt5/5.0.1/Src/qtbase/src/3rdparty/zlib" "LIBS+=-LC:/Qt/Qt5/5.0.1/Src/qtbase/src/3rdparty/zlib -lz"
mingw32-make
There is a full explanation in my blog if you want to check it out: http://www.antonioborondo.com/2014/10/22/zipping-and-unzipping-files-with-qt/

Here is what worked for me (QuaZip 0.7 on Windows 7 compiled with MSVC13 32 bits):
In the command line type:
SET INCLUDE=<PathToZib\include>;%INCLUDE%
SET LIB=<PathToZib\lib>;%LIB%
qmake PREFIX=<FolderWhereInstallWillPutFiles> LIBS+=<PathToZib\lib>/zdll.lib
nmake
nmake install
everything between <> must be changed to your applicable path
NOTE:
in the LIBS+= part use / instead of \ as folders delimiter

try to make the lib of quazip on windows - look here:
https://www.maefloresta.com/wiki/doku.php?id=quazip_windows
but - try the following command - instead of "make" take "mingw32-make".

Can't build a qt project using qtservice

I'm trying to use QtService from QtSolution in a Qt project.
I've unzipped it and run:
configure.bat -library
qmake
mingw32-make
the debug and release dll were placed inside C:\Qt\2010.03\qt\bin\
Examples were correctly built .
I added this line at the bottom of my .pro file:
include(../QtSolutions/qtservice/src/qtservice.pri)
and I was able to browse the qtservice's sources from the project source tree.
When I try to build my project I get:

What am I missing?

Windows XP SP3
QtService 2.6
Thank you for your time.

Just a guess: I don't see a include -IC:\Qt\2010.03\qt\include in your call of g++. So the compiler can't find the Qt Headers. I tink there is something wrong in your EMCSolutionCrawler.pro.
