cmd/link: Linking in Windows gives "malformed pe file: unexpected flags 0xe0500020 for PE section .text" #9794

Go version: 1.4
OS: Windows 8.1 64-bit
GOARCH: 386

Complete example:
https://github.com/rckclmbr/mingwtest

$ go build -x .
...
pack r $WORK/mingwtest.a $WORK/mingwtest/_obj/_cgo_import.8 $WORK/mingwtest/_obj/_cgo_defun.8 $WORK/mingwtest/_obj/_all.o # internal
cd .
/usr/src/go/pkg/tool/linux_amd64/8l -o $WORK/mingwtest/_obj/exe/a.out.exe -L $WORK -extld=i686-w64-mingw32-gcc $WORK/mingwtest.a
# mingwtest
/tmp/go-build284869168/mingwtest.a(_all.o): malformed pe file: unexpected flags 0xe0500020 for PE section .text
main._cgo_231fbd32956b_Cfunc_sp_error_message: _cgo_231fbd32956b_Cfunc_sp_error_message: not defined

Compiling and linking a c program using mingw works fine, it's just the go linker that isn't working.

The text was updated successfully, but these errors were encountered:

0xe0500020 means IMAGE_SCN_MEM_WRITE | IMAGE_SCN_MEM_READ | IMAGE_SCN_MEM_EXECUTE | IMAGE_SCN_CNT_CODE, which means _all.o has a writable .text section. We don't support this kind of writable .text section. Once #4069 is fixed, this issue should be gone too. Why do you link the .lib file in LDFLAGS? I don't think it will work.

rckclmbr · 2015-02-09T23:37:22Z

Thanks, @minux

I link to the .lib because the .dll doesn't work. I tested with a test c program to be sure, and it compiles with the .lib in LD_FLAGS

$ i686-w64-mingw32-gcc -I/usr/i686-w64-mingw32/include -o test.exe test.c ./libspotify.dll
/tmp/cchhcOOM.o:test.c:(.text+0x1e): undefined reference to `sp_error_message@4'
collect2: error: ld returned 1 exit status

vs

$ i686-w64-mingw32-gcc -I/usr/i686-w64-mingw32/include -o test.exe test.c ./libspotify.lib
# compiled and runs fine

I'll keep my eye on that ticket

Sadly, too late for Go 1.5.

@rckclmbr I tried building your program:

How do I resolve this error?

@alexbrainman Look at the Dockerfile, particularly where it says "Install libspotify for win32", and adjust for windows.

You may also need to change CFLAGS and LDFLAGS in main.go to the path you extracted libspotify to.

I don't have a readily available windows install I can give you more exact instructions, let me know if that's not enough for you and I'll get you better instructions.

I tried running your C example, but no luck. I copied some files into c_test directory and modified test.c:

    return 0;

What did I do wrong?
