I'd problems to build in ubuntu. I solved by installing the next packages.
When it built prompts the next warning
Deleting line 10 there were no warnings
There was a panic when it run without args
$ ./cgo-xslt Usage: ./cgo-xslt [options] stylesheet file [file ...] --param name value : pass a (parameter,value) pair panic: runtime error: index out of range [1] with length 1 goroutine 1 [running]: main.main() /home/sergio/pruebas/cgo-xslt/cgo-xslt.go:53 +0xf8Just added a return after usage
I ran a example with xsltproc to compare the result an was the same.
