I've installed gccgo using the distro package manager. It seems to work just fine except that I cannot run any tests.

==== jnml@e5-1650:~/src/modernc.org/crt> go-8 version

go version go1.10.3 gccgo (SUSE Linux) 8.2.1 20180831 [gcc-8-branch revision 264010] linux/amd64

==== jnml@e5-1650:~/src/modernc.org/crt>

The operating system here is openSUSE Leap 15.0/amd64. Gccgo was installed using package gcc8-go, version 8.2.1+r264010-lp150.2.3.

Does anybody know hot to get 'go-8 test' working?

Thanks in advance for any and all answers.

Can you send a link to the specific RPM you installed? Perhaps it is putting the "vet" tool in the wrong location.

Something to try:

% go test

...

% strace -f -o trace.txt go test

Then examine the trace output to locate the error ("no such tool"), walk back to see where it is trying to locate it, e.g. something like

198961 stat("/mumble/libexec/gcc/x86_64-pc-linux-gnu/9.0.0/vet", <unfinished ...>

198961 <... stat resumed> 0xc0001ace08) = -1 ENOENT (No such file or directory)

198951 futex(0xc000091120, FUTEX_WAIT_PRIVATE, 0, NULL <unfinished ...>

198961 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0

198961 write(2, "go tool: no such tool \"vet\"\n", 28) = 28

The package was installed using YAST (openSUSE GUI package manager). Package name is gcc8-go, package version is 8.2.1+r264010-lp150.2.3. I was not able to find the URL of the package.

Here it goes:

684 rt_sigaction(SIGSTKFLT, {sa_handler=SIG_DFL, sa_mask=~[RTMIN RT_1], sa_flags=SA_RESTORER|SA_ONSTACK|SA_RESTART|SA_SIGINFO, sa_restorer=0x7f256b1a9160}, <unfinished ...>

675 stat("/usr/lib64/gcc/x86_64-suse-linux/8/vet", <unfinished ...>
