Subject: [PATCH] gotools: fix compilation when making cross compiler | ||
|
||
libgo is "the runtime support library for the Go programming language. | ||
This library is intended for use with the Go frontend." | ||
|
||
gccgo will link target files with libgo.so which depends on libgcc_s.so.1, but | ||
the linker will complain that it cannot find it. That's because shared libgcc | ||
is not present in the install directory yet. libgo.so was made without problem | ||
because gcc will emit -lgcc_s when compiled with -shared option. When gotools | ||
were being made, it was supplied with -static-libgcc thus no link option was | ||
provided. Check LIBGO in gcc/go/gcc-spec.c for how gccgo make a builtin spec | ||
for linking with libgo.so | ||
|
||
- GccgoCrossCompilation, https://github.com/golang/go/wiki/GccgoCrossCompilation | ||
- Cross-building instructions, http://www.eglibc.org/archives/patches/msg00078.html | ||
|
||
When 3-pass GCC compilation is used, shared libgcc runtime libraries will be | ||
available after gcc pass2 completed and will meet the gotools link requirement | ||
at gcc pass3 | ||
