I am integrating Firebase in my app according to the instructions and added [FIRApp configure]; in the code however, while compiling the app I am getting the following error:
Undefined symbols for architecture armv7:
"_OBJC_CLASS_$_FIRApp", referenced from:
objc-class-ref in AppDelegate.o
ld: symbol(s) not found for architecture armv7
Did CocoaPods write any warnings due to pods installation? I fixed a similar issue by setting OTHER_LDFLAGS build settings to $(inherited) flag.
s.static_framework = true
to podspec worked for me
URL: How to use Firebase SDK as a Pod dependency?
Updating the pod "Architectures" to $(ARCHS_STANDARD) worked for me.
Put
$(inherited) -ObjC -framework "AVFoundation" -framework "AudioToolbox" -framework "CFNetwork" -framework "CoreGraphics" -framework "CoreMedia" -framework "CoreMotion" -framework "CoreTelephony" -framework "CoreVideo" -framework "GLKit" -framework "GoogleMobileAds" -framework "MediaPlayer" -framework "MessageUI" -framework "MobileCoreServices" -framework "OpenGLES" -framework "QuartzCore" -framework "Security" -framework "StoreKit" -framework "SystemConfiguration" -weak_framework "AdSupport" -weak_framework "JavaScriptCore" -weak_framework "SafariServices" -weak_framework "WebKit"

I am trying to install Rcplex following the steps in http://jrzubizarreta.com/INSTALL. I have already correctly located the CFLAGS and CLNFLAGS in the makefile. However, when I run the installation code as described at the link from the folder where I installed Rcplex,
cd /Users/112186/Downloads/Rcplex
R CMD INSTALL --configure-args="PKG_CFLAGS='-m64 -fPIC' PKG_CPPFLAGS=-I/Applications/CPLEX_Studio129/cplex/include PKG_LIBS='-L/Applications/CPLEX_Studio129/cplex/lib/x86-64_osx/static_pic -lcplex -m64 -lm -lpthread -framework CoreFoundation -framework IOKit'" Rcplex
I get the error:
Warning: invalid package ‘Rcplex’
Error: ERROR: no packages specified
Any idea why I get this error? How to fix it? Thank you!
While following test case example, I stuck at making.
My procedure is as below.
~/Qt/5.12.2/clang_64/bin/qmake -project "QT +=testlib"
=> it generated Testcase.pro
~/Qt/5.12.2/clang_64/bin/qmake
=> Makefile was generated
~/Qt/5.12.2/clang_64/bin/moc -o testqstring.moc testqstring.h
=> testqstring.moc was generated
make
=> moc_predefs.h and moc_testqstring.cpp were generated, and print error as below.

What did I mistake?
I'm trying to install the python library rpy2 in OS X (El Capitan) with R 3.4.
I did follow many posts on web and I end up replacing clang from xcode to one manually installed (after following http://thecoatlessprofessor.com/programming/openmp-in-r-on-os-x/#clang-before-3-4-0):
clang version 4.0.0 (tags/RELEASE_400/final)
Target: x86_64-apple-darwin15.5.0
Thread model: posix
InstalledDir: /usr/bin
Still, when I tried to install rpy2 (sudo pip3 install rpy2):
clang -bundle -undefined dynamic_lookup build/temp.macosx-10.11-x86_64-3.6/./rpy/rinterface/_rinterface.o -L/usr/local/lib -L/usr/local/lib -L/usr/local/opt/openssl/lib -L/usr/local/opt/sqlite/lib -Lbuild/temp.macosx-10.11-x86_64-3.6 -L/usr/local/lib -lpcre -llzma -lbz2 -lz -licucore -lm -liconv -lr_utils -o build/lib.macosx-10.11-x86_64-3.6/rpy2/rinterface/_rinterface.cpython-36m-darwin.so -fopenmp -F/Library/Frameworks/R.framework/.. -framework R
ld: library not found for -lomp
clang-4.0: error: linker command failed with exit code 1 (use -v to see invocation)
error: command 'clang' failed with exit status 1
What's lomp? I'm not sure what I can do now.
UPDATE:
I try to reinstall llvm through brew:
brew reinstall --with-clang --with-lld --with-python --HEAD llvm
now installing rpy2 I got:
clang -bundle -undefined dynamic_lookup build/temp.macosx-10.11-x86_64-3.6/./rpy/rinterface/_rinterface.o -L/usr/local/lib -L/usr/local/lib -L/usr/local/opt/openssl/lib -L/usr/local/opt/sqlite/lib -Lbuild/temp.macosx-10.11-x86_64-3.6 -L/usr/local/lib -lpcre -llzma -lbz2 -lz -licucore -lm -liconv -lr_utils -o build/lib.macosx-10.11-x86_64-3.6/rpy2/rinterface/_rinterface.cpython-36m-darwin.so -fopenmp -F/Library/Frameworks/R.framework/.. -framework R
ld: library not found for -lomp
clang-6.0: error: linker command failed with exit code 1 (use -v to see invocation)
error: command 'clang' failed with exit status 1
Although from the llvm installation I got the advice:
For compilers to find this software you may need to set:
LDFLAGS: -L/usr/local/opt/llvm/lib
CPPFLAGS: -I/usr/local/opt/llvm/include
do you know how to set it? It may be the reason it fails
This was discussed on the rpy2 issue tracker: https://bitbucket.org/rpy2/rpy2/issues/403/cannot-pip-install-rpy2-with-latest-r-340
Note that the issue was resolved and a precompiled binary wheel for rpy2-2.9.3 is now available on pypi.
actually, my goal is to use ffmpeg on Qt platform. But tow of them is unfamiliar with me..
I tried command on ./ffmpeg directory after build (./configure, make, sudo make install) as below on Mac (os x) 10.12.4 (Sierra)
$ gcc ffmpeg.c -o a.out -I /usr/local/include -I /Users/koseonjae/ffmpeg -L /usr/local/lib -lavdevice -lavutil -lavformat -lavcodec -lavutil -lx264 -lvpx -lvorbisenc -lvorbis -ltheoraenc -ltheoradec -logg -lmp3lame -lbz2 -lz -lxslt -lfdk-aac -liconv -lopus -lx265 -lxvidcore -lpng16 -lswresample -framework CoreFoundation -framework CoreServices -framework AudioUnit -framework AudioToolbox -framework CoreAudio -framework AVFoundation -framework CoreMedia -framework CoreVideo -framework CoreAudio -framework Foundation -framework Security -framework VideoDecodeAcceleration -framework VideoToolbox
I added many library, but result is as below
/Users/koseonjae/ffmpeg/ffmpeg2.h:157:8: error: unknown type name 'BOOL'
static BOOL WINAPI CtrlHandler(DWORD fdwCtrlType);
/Users/koseonjae/ffmpeg/ffmpeg2.h:157:19: error: expected ';' after top level declarator
static BOOL WINAPI CtrlHandler(DWORD fdwCtrlType);
what library should I add?? thank you!
This question is not about Qt, but about compiling ffmpeg on a Mac.
Read on about detailed installation of ffmpeg dependencies: https://trac.ffmpeg.org/wiki/CompilationGuide/MacOSX .
I am trying to get a working R environnement on my mac.

I had exactly the same problem, and finally resolved, via a solution I found here.
The new Mac OS X (10.11, El Capitan) has trouble with env variables.
The newest dev flavor of rJava manages to handle things correctly. Here is what I did to resolve it:
Download version 0.9-8 (rJava_0.9-8.tar.gz) from here
Install it from the downloaded source:
$ R CMD INSTALL ~/Downloads/rJava_0.9-8.tar.gz
(Or wherever you put it)
That's all it took!
