I'm rediscovering the horror of compiling C. I just installed libtins
from http://libtins.github.io, following the usual ./configure
-> make
-> sudo make install
pattern.
sudo make install
definitely put headers in /usr/local/include/tins
but it doesn't seem like g++
is able to see them.
following the advice here, I tried running gcc -x c++ -v -E /dev/null
in order to see the include paths.
clang -cc1 version 5.1 based upon LLVM 3.4svn default target x86_64-apple-darwin13.3.0
ignoring nonexistent directory "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/local/include"
ignoring nonexistent directory "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/Library/Frameworks"
#include "..." search starts here:
#include <...> search starts here:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../lib/clang/5.1/include
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/System/Library/Frameworks (framework directory)
End of search list.
I would have expected to see /usr/local/include
in there somewhere. Are the default paths paths all inside the Xcode app now?
app.cpp
#include <tins/tins.h>
int main() {
return 1;
}
compile command
g++ app.cpp -ltins
result
app.cpp:3:10: fatal error: 'tins/tins.h' file not found
Any idea how to make g++
see the headers?

You didn't set the include path when compiling. Hence, the correct compilation line should be:
g++ app.cpp -I/usr/local/include -L/usr/local/lib -ltins
