how to build static program with gccgo
问题
我在使用gccgo构建静态程序版本时遇到了问题。
1> 使用go build命令：
go build -compiler gccgo -gccgoflags '-static -L/lib64' test.go
结果：
/usr/bin/ld: 找不到 -lgo
/usr/bin/ld: 找不到 -lpthread
/usr/bin/ld: 找不到 -lm
/usr/bin/ld: 找不到 -lc
2> 使用gccgo build命令：
gccgo -o test_gccgo_yes -static -L/lib64 test.go
结果：
/usr/bin/ld: 找不到 -lgo
/usr/bin/ld: 找不到 -lpthread
/usr/bin/ld: 找不到 -lm
/usr/bin/ld: 找不到 -lc
3> 如果我不使用静态编译：
gccgo -o test_gccgo_yes -g test.go
结果：
ldd test_gccgo_yes
显示test_gccgo_yes是一个动态文件
请问如何使用gccgo构建静态程序？
英文:
I has a prblem when I use gccgo to build static programe version
1> use go build
go build -compiler gccgo -gccgoflags '-static -L/lib64' test.go
result:
/usr/bin/ld: cannot find -lgo
/usr/bin/ld: cannot find -lpthread
/usr/bin/ld: cannot find -lm
/usr/bin/ld: cannot find -lc
2>use gccgo build
gccgo -o test_gccgo_yes -static -L/lib64 test.go
result:
/usr/bin/ld: cannot find -lgo
/usr/bin/ld: cannot find -lpthread
/usr/bin/ld: cannot find -lm
/usr/bin/ld: cannot find -lc
3> if I don't use static to compile it
gccgo -o test_gccgo_yes -g test.go
result :
ldd test_gccgo_yes
show test_gccgo_yes is dynamic file
How I can build static program with gccgo?

如果你使用static关键字，那么gccgo需要每个库的静态版本，例如libc.a而不是动态库libc.so。
安装你的发行版的静态包。在CentOS 7上，它们的名称是glibc-static和libgo-static。然后你应该能够构建（你也不需要-L标志）。
然而，即使在那之后，你可能仍然会遇到一些警告和可能的错误。例如，在构建一个这样的静态应用程序时，我遇到了以下错误：
/usr/lib/gcc/x86_64-redhat-linux/4.8.5/libgo.a(net.o): In function `net.lookupPort':
(.text+0x48e2): warning: Using 'getaddrinfo' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking
/usr/bin/ld: dynamic STT_GNU_IFUNC symbol `strcmp' with pointer equality in `/usr/lib/gcc/x86_64-redhat-linux/4.8.5/../../../../lib64/libc.a(strcmp.o)' can not be used when making an executable; recompile with -fPIE and relink with -pie
因此，可能需要更多的工作来获得一个可工作的静态二进制文件。请参阅https://www.akkadia.org/drepper/no_static_linking.html。
英文:
If you're using static then gccgo requires the static versions of each library i.e. libc.a rather than the dynamic libs libc.so.
Install your distro's static packages. On CentOS 7, they are named glibc-static and libgo-static. Then you should be able to build (you won't need the -L flag either)
However, you may still get some warnings and possibly errors after that. For example when building one such static application I got these errors:
/usr/lib/gcc/x86_64-redhat-linux/4.8.5/libgo.a(net.o): In function `net.lookupPort':
(.text+0x48e2): warning: Using 'getaddrinfo' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking
/usr/bin/ld: dynamic STT_GNU_IFUNC symbol `strcmp' with pointer equality in `/usr/lib/gcc/x86_64-redhat-linux/4.8.5/../../../../lib64/libc.a(strcmp.o)' can not be used when making an executable; recompile with -fPIE and relink with -pie
So more work may be required to get a working static binary. See https://www.akkadia.org/drepper/no_static_linking.html
