Wanted to test etcd from  AIX Toolbox for Linux Applications - Downloads alpha which is written in go so also (assumedly need go runtime).

I'm not our admin on the machine, but had him do the download/installs, but etcd fails to run with following message...

$ /opt/freeware/bin/etcd
exec(): 0509-036 Cannot load program etcd because of the following errors:
0509-130 Symbol resolution failed for etcd because:
0509-136 Symbol gcbits..DGGpa (number 251) is not exported from
dependent module /opt/freeware/lib/libgo.a[libgo.so.13].
0509-192 Examine .loader section symbols with the
'dump -Tv' command.

also added /opt/freeware/lib to front of LIBPATH and no difference.

Also did ar xv /opt/freeware/lib/libgo.a and libgo.so.13 was the version in the archive. 

Also did dump -Tv /opt/freeware/lib/libgo.a | grep gcbits..DGGpa
[438] 0x107bafe4 .text wEXP RO Ldef [noIMid] gcbits..DGGpa

although I'm not sure what wEXP vs EXP means

Can anyone help on this etcd start up fail?

Looks like the 64bit version of the gcc-go library is not exporting the symbol ( /opt/freeware/bin/etcd is a 64bit binary)

# dump -X64 -Tv /opt/freeware/lib/libgo.a | grep DGGpa

# dump -Tv /opt/freeware/lib/libgo.a | grep DGGpa
[438] 0x107bafe4 .text wEXP RO Ldef [noIMid] gcbits..DGGpa

We will check why it is not exported in the recent gcc-go version.
