Description Cristian Gafton 2012-10-11 04:29:55 EDT
F16 came with gcc-4.6.2 and the libgo package shipped a libgo.so.0.0.0 runtime library.

Compiling a simple hello world binary on F16 against that libgo worked okay:

bash$ cat hello.go
package main
import "fmt"
func main() {
  fmt.Println("Hello, world")
bash$ gccgo -o hello hello.go
bash$ ./hello
Hello, world

Now, if we install the libgo-4.7.2 package out of F17 (which provides the same libgo.so.0.0.0 runtime library), when running the previously compiled binary I get:

bash$ ./hello
./hello: symbol lookup error: ./hello: undefined symbol: libgo_os.os.Envs

Clearly the two libgo.so.0.0.0 libraries are not compatible - as such, the soname versioning should reflect that.
Comment 1 Fedora End Of Life 2013-07-03 18:50:10 EDT
This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '17'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 17's end of life.

Bug Reporter:  Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 17 is end of life. If you 
would still like  to see this bug fixed and are able to reproduce it 
against a later version  of Fedora, you are encouraged  change the 
'version' to a later Fedora version prior to Fedora 17's end of life.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.
Comment 2 Fedora End Of Life 2013-07-31 21:00:07 EDT
Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
