Sure. See the Makefile at the end of this mail. Please note that I don't
really know what I'm doing here -- just tried a few things and tried to
make sense of error messages until I got working binaries.
I put symlinks to the index, sparse, regexp directories into
src/code.google.com/p/codesearch and added -Isrc to every gccgo
invocation, so that the compiler looks for the local imports in the
right place. For the shared libraries, I added
1. -shared -fPIC
2. -fno-split-stack
Otherwise I could not link executables and got the following error
message:
/usr/bin/ld.bfd.real: cindex: hidden symbol `__morestack' in
/usr/lib/gcc/x86_64-linux-gnu/4.7/libgcc.a/morestack.o) is referenced
by DSO
/usr/bin/ld.bfd.real: final link failed: Bad value
When the libraries are put into
src/code.google.com/codesearch/lib{sparse,regexp,index}.so, they are
subsequently found by the compiler -- and apparently used for imports,
even if the source files are missing.
I have not yet figured out how to specify the full namespace-related
path to the linker yet: -lcode.google.com/p/codesearch/index causes ld
then to look for libcode.google.com/p/codesearch/index.so which is
almost but not quite what is needed.
Cheers,
