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

|
||
|
|
|
||
|
|
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
