address-model=32 --with-context causes the Boost build to break on Mac OS X. Just found https://svn.boost.org/trac/boost/ticket/7110 ; may or may not be the same issue. The specific assembler error messages differ. code should work - see the regression tests at http://www.boost.org/development/tests/release/developer/context.html

Now we would like to introduce Boost.Context. However, address-model=32 --with-context causes the Boost build to break on Mac OS X.

I think address-model=32 is not necessary: bjam toolset=<> should work

In our case, toolset=darwin, yes. However, on a 64-bit Mac, this only builds address-model-64. When I pass address-model=32, I get: libs/context/src/asm/fcontext_i386_sysv_macho_gas.S:70:suffix or operands invalid for `jmp' libs/context/src/asm/fcontext_i386_sysv_macho_gas.S:82:suffix or operands invalid for `push' libs/context/src/asm/fcontext_i386_sysv_macho_gas.S:83:suffix or operands invalid for `push' libs/context/src/asm/fcontext_i386_sysv_macho_gas.S:84:suffix or operands invalid for `push' libs/context/src/asm/fcontext_i386_sysv_macho_gas.S:86:suffix or operands invalid for `pop' libs/context/src/asm/fcontext_i386_sysv_macho_gas.S:87:Missing operand value assumed absolute 0. libs/context/src/asm/fcontext_i386_sysv_macho_gas.S:87:junk `[.-1b]' after expression libs/context/src/asm/fcontext_i386_sysv_macho_gas.S:88:junk `@PLT' after expression libs/context/src/asm/fcontext_i386_sysv_macho_gas.S:90:suffix or operands invalid for `pop' libs/context/src/asm/fcontext_i386_sysv_macho_gas.S:91:suffix or operands invalid for `pop' libs/context/src/asm/fcontext_i386_sysv_macho_gas.S:92:suffix or operands invalid for `pop' libs/context/src/asm/fcontext_i386_sysv_macho_gas.S:101:suffix or operands invalid for `pop' libs/context/src/asm/fcontext_i386_sysv_macho_gas.S:112:suffix or operands invalid for `pop' libs/context/src/asm/fcontext_i386_sysv_macho_gas.S:113:Missing operand value assumed absolute 0. libs/context/src/asm/fcontext_i386_sysv_macho_gas.S:113:junk `[.-3b]' after expression libs/context/src/asm/fcontext_i386_sysv_macho_gas.S:116:suffix or operands invalid for `push' libs/context/src/asm/fcontext_i386_sysv_macho_gas.S:117:junk `@PLT' after expression I need to build a 32-bit Context library even on a 64-bit build machine. Is this possible?

should work on Mac OS X - take a look at http://www.boost.org/development/tests/release/developer/context.html tests are OK

None of them seem to specify address-model, so presumably they're defaulting to the current architecture. I don't know if they're running on 32-bit or 64-bit machines.

yes - it should, unfortunately 1.51.0 contains an error for 32bit Mac OSX. Could you try the trunk or release branch from svn (32bit and 64bit)?

I checked out the Subversion trunk. This command: ./b2 toolset=darwin address-model=32 architecture=x86 variant=release link=static stage produces these errors: Jamfile.gas bin.v2/libs/context/build/darwin-4.2.1/release/address-model-32/architecture-x86/link-static/threading-multi/asm/make_i386_sysv_macho_gas.o libs/context/src/asm/make_i386_sysv_macho_gas.S:38:suffix or operands invalid for `push' libs/context/src/asm/make_i386_sysv_macho_gas.S:62:suffix or operands invalid for `pop' libs/context/src/asm/make_i386_sysv_macho_gas.S:68:suffix or operands invalid for `pop' as -o "bin.v2/libs/context/build/darwin-4.2.1/release/address-model-32/architecture-x86/link-static/threading-multi/asm/make_i386_sysv_macho_gas.o" "libs/context/src/asm/make_i386_sysv_macho_gas.S" Jamfile.gas bin.v2/libs/context/build/darwin-4.2.1/release/address-model-32/architecture-x86/link-static/threading-multi/asm/jump_i386_sysv_macho_gas.o libs/context/src/asm/jump_i386_sysv_macho_gas.S:70:suffix or operands invalid for `jmp' as -o "bin.v2/libs/context/build/darwin-4.2.1/release/address-model-32/architecture-x86/link-static/threading-multi/asm/jump_i386_sysv_macho_gas.o" "libs/context/src/asm/jump_i386_sysv_macho_gas.S" My colleague found that if we execute the above 'as' commands, adding '-arch i386', they each succeed: as -arch i386 -o "bin.v2/libs/context/build/darwin-4.2.1/release/address-model-32/architecture-x86/link-static/threading-multi/asm/make_i386_sysv_macho_gas.o" "libs/context/src/asm/make_i386_sysv_macho_gas.S" as -arch i386 -o "bin.v2/libs/context/build/darwin-4.2.1/release/address-model-32/architecture-x86/link-static/threading-multi/asm/jump_i386_sysv_macho_gas.o" "libs/context/src/asm/jump_i386_sysv_macho_gas.S" So perhaps there's a Jamfile error somewhere. Once those 'as' commands have succeeded, repeating the above './b2' command succeeds as well, producing stage/lib/libboost_context.a. With that library, I can compile and link the exit.cpp example. However, it produces a segmentation fault: cd libs/context/example g++ -I ../../.. -L ../../../stage/lib -arch i386 -m32 -o exitprog exit.cpp -lboost_context && ./exitprog main: call start_fcontext( & fcm, fc1, 0) f1: entered f1: call jump_fcontext( fc1, fc2, 0) f2: entered f2: call jump_fcontext( fc2, fc1, 0) f1: return /bin/bash: line 1: 3034 Segmentation fault: 11 ./exitprog The name of the function in which the fault occurs is suggestive: gdb exitprog GNU gdb 6.3.50-20050815 (Apple version gdb-1752) (Sat Jan 28 03:02:46 UTC 2012) Copyright 2004 Free Software Foundation, Inc.
