libs/context/src/asm/make_i386_sysv_macho_gas.S fails to compile under OSX

[cowwoc@…]

This issue was originally reported against 1.51.0 at ​http://boost.2283326.n4.nabble.com/Context-Building-32-bit-Context-td4636075.html by someone else but it doesn't look like it was ever fixed. I can reproduce it under 1.53.0.

When compiling the "context" module under OSX, I get the following compiler error:

darwin.compile.asm bin.v2/libs/context/build/5c5d610e2c3c5c3698138625c22860e2/asm/make_i386_sysv_macho_gas.o libs/context/src/asm/make_i386_sysv_macho_gas.S:59:suffix or operands invalid for `pop'

Are you shure your env is correct? I got the info from other develoeprs that the code is working on 32bit Mac OS X.

'jmp *%edx' and 'popl %ecx' is legal assembler on 32bit i386 Mac OS X.

For me it seams that something is wired with your build.

BTW: If 32bit Mac OS X is so important than contribute regression tests for boost-trunk. This would help to prevent releasing bugs in boost. Till today 32bit Mac OS X has no regression tests - mabye 32 bit Mac OS X will be marked as not supported in the future.

Today, I got the info from other developers that boost.context (1.53) works on 32bit Mac OS X, so I'll close this bug report as 'works for me'.

Sorry for not replying earlier but I believe you need to reopen this issue. I am invoking:

bjam address-model=32 --stagedir=. --without-python --without-mpi --layout=system variant=debug link=shared threading=multi runtime-link=shared stage -j 2 --hash

on Mountain Lion. So, I'm building Boost 32-bit under a 64-bit OS.

Yes, but command line `"g++" -x assembler-with-cpp -O0 -fno-inline -Wall -g -dynamic -gdwarf-2 -fexceptions -fPIC -DBOOST_ALL_NO_LIB=1 -DBOOST_CONTEXT_DYN_LINK=1 -I"." -c -o...' compile for default architecture, i.e. x86_64 architecture on modern 64bit Mac.

Replying to Gili <cowwoc@…>:

Probably, that not right, for example:

leom-3:boost-trunk leo$ uname -a
Darwin leom-3.local 12.2.0 Darwin Kernel Version 12.2.0: Sat Aug 25 00:48:52 PDT 2012; root:xnu-2050.18.24~1/RELEASE_X86_64 x86_64
leom-3:boost-trunk leo$ ./bjam address-model=32 --stagedir=xyz --without-python --without-mpi --layout=system variant=debug link=shared threading=multi runtime-link=shared stage -j 2 --hash
...
leom-3:boost-trunk leo$ file xyz/lib/*
xyz/lib/libboost_atomic.dylib:     Mach-O 64-bit x86_64 dynamically linked shared library
xyz/lib/libboost_chrono.dylib:     Mach-O 64-bit x86_64 dynamically linked shared library
...

IMHO, this bug - bug in "tools/build/v2/tools/darwin.jam"

Sorry for my best English

[Serguei E. Leontiev <leo@…>]

P.S.

Workaround - add to end file "tools/build/v2/user-config.jam" next string:

using darwin : : c++ -arch i386 : : ;

[cowwoc@…]

Okay, so why is this ticket still closed? Shouldn't you reopen it?

[anonymous]

Because argument "address-model=32" for toolset darwin on modern 64-bit Mac OSX create ALL libraries, tests, examples, etc. as x86_64.

IMHO more suitable create new ticket for component "Building Boost"

[Serguei E. Leontiev <leo@…>]

P.S. This work for me, because I use MacPorts on my Mac. MacPorts patch jam files for resolve this issue.

[Gili <cowwoc@…>]

Can you please reopen this issue and change component to "Building Boost"?
