How to install Boost with specified compiler (say GCC)

Question

I would like to install boost with specified compilers, such as the gcc-4.9.1 that I have installed in . The curren

Answer 1

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

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.
