How to install Boost with specified compiler (say GCC) - c++

Question

I would like to install boost with specified compilers, such as the gcc-4.9.1 that I have installed in <gcc_49_root>. The current OS is Mac OS X 10.9.4, but I would like this installation process to work on other OS. The documentation of boost is quite opaque about this scenario. What I have tried is as following:
$ ./bootstrap.sh
-n Building Boost.Build engine with toolset darwin...
tools/build/src/engine/bin.macosxx86_64/b2
-n Detecting Python version...
2.7
-n Detecting Python root...
/System/Library/Frameworks/Python.framework/Versions/2.7
-n Unicode/ICU support for Boost.Regex?...
not found.
Generating Boost.Build configuration in project-config.jam...
Insert using gcc : 4.9.1 : <gcc_49_root>/bin/g++-4.9 : ; into project-config.jam.
$ ./b2 --prefix=<...> toolset=gcc-4.9.1 install
But encountered the errors:

What should I do with these errors? Thanks in advance!

Answer 1

Apple's linker ld(ld64) is different from other UNIX/GNU linkers and does not support some options, such as -h(soname), --start-group, --end-group, etc,. Those errors you got("unknown option") were the results of trying to pass non-supported flags to Apple's ld when you specify the gcc toolset.
The way I hacked mine was to first include "darwin" in the project config file:
using gcc : 4.9.1 : <gcc_49_root>/bin/g++-4.9 : <linker-type>darwin ;
Next removing the non-supported flags from {BOOST_DIR}/tools/build/src/tools/gcc.jam, from the long command in the "actions link.dll bind LIBRARIES" block:
remove/comment out this portion:
... $(HAVE_SONAME)-Wl,$(SONAME_OPTION)$(SPACE)-Wl,$(<[-1]:D=) ...
Afterwards the Boost libraries built without errors and worked fine in other gcc4.9 compiled codes.
$ ./bootstrap.sh --with-toolset=gcc
$ ./b2 --toolset=gcc-4.9.1
UPDATE (May 2015): I recently did a new built of gcc 5.1.0 and Boost 1.58.0 on Yosemite (10.10.1). Same fix worked for me.

Answer 2

I am using Mac Yosemite and this worked for me.
Open "tools/build/example/user-config.jam" and change
# Configure gcc (default version).
# using gcc ;
# Configure specific gcc version, giving alternative name to use.
using darwin : 5 : g++-5 ;
Then open "tools/build/src/tools/darwin.jam" then delete below line (this step may not be required. just try both way);
"$(CONFIG_COMMAND)" -dynamiclib -Wl,-single_module -install_name "$(<:B)$(<:S)" -L"$(LINKPATH)" -o "$(<)" "$(>)" "$(LIBRARIES)" -l$(FINDLIBS-SA) -l$(FINDLIBS-ST) $(FRAMEWORK_PATH) -framework$(_)$(FRAMEWORK:D=:S=) $(OPTIONS) $(USER_OPTIONS)
As last step, compile and install
$ ./bootstrap.sh --with-libraries=all --with-toolset=darwin --prefix=/usr/local/boost_for_gcc
$ ./b2
$ ./b2 install
Now you can compile your code like below
$ g++ -o main main.cpp -L/usr/local/boost_for_gcc/lib -I/usr/local/boost_for_gcc/include -lboost_regex
