Compiling on OSX fails about go-sqlite3 HOT 11 CLOSED

Probably, your sqlite3.pc contains gcc's feature not clang's one. And I noticed your build log contains pkg-config outputs. go-sqlite3 doesn't use pkg-config any more.

from go-sqlite3.

I tried it again and the pkg-config outputs are gone. The error is the same. It seems this could be a bug in cgo:

If I add "-Qunused-arguments" to CFLAGS like it's suggested on stackoverflow, I'm just getting a lot of errors like: "could not determine kind of name for C.sqlite3_column_count"

from go-sqlite3.

This appears to be a bug in cgo that does not look like it's going to be resolved soon. However, installing gcc-4.2 (the last "real" gcc) and putting it before /usr/bin/gcc in my PATH appears to have solved the problem.

EDIT: Also, passing -ldflags -linkmode=external as an argument to go build (or whatever) was necessary to force the native linker (which is necessary to link to the sqlite3 library).

from go-sqlite3.

I'm hitting this, too.

According to this comment, this is fixed in 1.2 as well as HEAD.

from go-sqlite3.

I installed Go HEAD and confirmed that this error no longer occurs.

from go-sqlite3.

I can confirm this is a issue with the installed gcc for OSX. I am on 10.8, Go 1.1.2.

Fix for the issue:

1. install gcc with homebrew
2. move /usr/local/bin is at the top of /etc/paths, if not already. (Open a new terminal after)
3. Navigate to /usr/local/bin and run sudo ln -s gcc-4.x gcc, makes sure that you put in the version of gcc that you are using.

This resolved the issue for me.

P.S

you may have to run go install -ldflags -linkmode=external to use the new version of gcc correctly

from go-sqlite3.

Cool. So I can close this issue on the release of 1.2 ?

from go-sqlite3.

@mattn I think so. The issue is not with your library. I left my instructions for historical purposes.

from go-sqlite3.

There is a way to avoid symlinking by creating an alias in .bash_profile

alias go="env CC=GCC-4.2 go"

Go will use proper gcc compiler and other things won't be affected.

from go-sqlite3.

Same as with #95, this has been fixed in Go 1.2 (I am using 10.9.1)
