I'm unable to compile go-sqlite3 with gccgo for the PowerPC plataform.

What version of Go are you using (go version)?

go version go1.8.3 gccgo (Ubuntu 7.2.0-8ubuntu3) 7.2.0 linux/amd64

Does this issue reproduce with the latest release?

I have not tested with the latest since the above is the highest version available as pre-compiled package in Ubuntu

What operating system and processor architecture are you using (go env)?

Cross-compiling to ppc with gccgo

C compiler:

powerpc-fsl-linux-gnuspe-gcc --version
powerpc-fsl-linux-gnuspe-gcc (GCC) 4.9.2

What did you do?

Attempt to install go-sqlite3:

GCCGO=powerpc-linux-gnuspe-gccgo CGO_ENABLED=1 GOARCH=ppc CGO_ENABLED=1 go-7 get -x github.com/mattn/go-sqlite3

What did you expect to see?

Package compiling

What did you see instead?

Compilation fails with

In file included from cgo-c-prolog-gccgo:1:0:
/opt/fsl/2.0/sysroots/x86_64-fslsdk-linux/usr/lib/powerpc-fsl-linux/gcc/powerpc-fsl-linux/4.9.2/include/stdint.h:9:26: fatal error: stdint.h: No such file or directory
 # include_next <stdint.h>
                          ^
compilation terminated.

The compiler I'm using requires some flags to work, in particular the --sysroot flag. This is specified in the CC variable which currently is:

powerpc-fsl-linux-gnuspe-gcc -m32 -mcpu=8548 -mabi=spe -mspe -mfloat-gprs=double --sysroot=/opt/fsl/2.0/sysroots/ppce500v2-fsl-linux-gnuspe

The above works with the older go version go1.4.2 gccgo (Ubuntu 5.4.0-6ubuntu1~16.04.5) 5.4.0 20160609 linux/amd64. However, with the version indicated above, the compilation fails because go does not include the flags specified in the CC variable. I managed to work around this by setting CGO_CFLAGS and CGO_LDFLAGS, as can be viewed above. However, I still get a compilation error, because apparently gccgo (or cgo?) is not including the CGO_CFLAGS when compiling _cgo_defun.c as can be viewed in the verbose output below:

Observe that the last compiler invocation did not include the contents of CGO_CFLAGS, preventing --sysroot being passed which messes the include path and makes compilation fail.

That suggestion isn't exactly right, as we should also be using the package local #cgo CFLAGS: when compiling _cgo_defun.c.

Is there a work around for this? Or just wait for Go1.11?

I think it works to add the options to the CC environment variable.

The workaround for the CC environment variable does seem to work for me. Any ideas what I'm doing wrong?

I haven't tested with newer gccgo versions, but in my original report the whole problem resulted from gccgo not using the flags specified in CC anymore, just the binary path. Maybe that's a separate bug?
