OSXCROSS BUGS
ISSUE:
GCH generation does not work with gcc
or clang++-gstdc++
/-foc-use-gcc-libstdc++
if -c
or -x<lang>-header
is not passed to the compiler.
Example:
$ o64-gcc test.h
Undefined symbols for architecture x86_64:
"_main", referenced from:
start in crt1.10.6.o
This is due to -Wl,-no_compact_unwind
being passed to the compiler under the hood.
Example:
$ x86_64-apple-darwin14-base-gcc
x86_64-apple-darwin14-base-gcc: fatal error: no input files
$ x86_64-apple-darwin14-base-gcc -Wl,-no_compact_unwind
Undefined symbols for architecture x86_64:
"_main", referenced from:
start in crt1.10.6.o
ld: symbol(s) not found for architecture x86_64
WORKAROUND:
Add -c
or -x<lang>-header
to the compiler flags.
Example:
o64-clang++-gstdc++ test.hpp # BAD
o64-clang++-gstdc++ -xc++-header test.hpp # OK
o64-clang++-gstdc++ test.hpp -c # OK
o64-g++ test.hpp -c # OK
