| 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 | |||||
