Trouble installing this package #22

Closed dimitriadamou closed 8 years ago

dimitriadamou commented 8 years ago

Hey there,

I am running MacOS, Go 1.7, running "go get github.com/lestrrat/go-libxml2" I get

'libxml/HTMLparser.h' file not found

include <libxml/HTMLparser.h>

I have done sudo brew install libxml2 and etc

I have made an alias to "libxml" inside my /usr/local/include/

I can't seem to figure out how to check where the default include path is when using go get, I can compile fine under GCC (not the Go library though)

I have worked with libxml in C before and it has worked, but I can't figure it out using Go; any help would be appreciated.

Edit:

It seems like Go expects my include path to be /usr/include/ - GCC was fine.

It wouldn't accept it as an alias so I had to copy the whole of /usr/local/include/ into /usr/include/

PS before copying my include folder into /usr/include - I tried go get -gccgoflags -I/usr/local/include,-I/usr/local/include/libxml2 ... and had the same issue.

Do you happen to know if I can reconfigure go to look in /usr/local/include instead ? Apart from that - library works great now 👯

Forgot to close, sorry.

Sorry for the late reply, but maybe you have a .pc (pkg-config file) somewhere in the discoverable path that points to /usr/include of /usr/local/include? Or, maybe you don't have a .pc file that points to /usr/local/include?

cgo isn't terrible smart about finding paths and what not, and mostly relies on stuff like pkg-config to find those things

dimitriadamou commented 8 years ago

All good, I didn't have much luck with pkg-config it was pointing to some where else, how ever the current setup is working so I'll leave as is for now

Had this same problem on MacOS with libxml2 installed via brew.

PKG_CONFIG_PATH=/usr/local/opt/libxml2/lib/pkgconfig go get github.com/lestrrat-go/libxml2 worked for me.
