gcc issue on windows 64

[arulrajalivi]

While trying to do "go install github.com/mattn/go-sqlite3"
I am getting the follwoing error. In one of the issues someone mentioned that we don't need gcc if we install go-sqlite3. Any help would be greatly appreciated.

github.com/mattn/go-sqlite3

exec: "gcc": executable file not found in %PATH%

Thanks

[mattn]

please type where gcc in your cmd.exe

[arulrajalivi]

Added C:/cygwin/bin to the %PATH% and I can see gcc.exe in that location. Now I a getting the below error. when do a go build

github.com/mattn/go-sqlite3

/usr/lib/gcc/x86_64-pc-cygwin/4.9.2/../../../../x86_64-pc-cygwin/bin/ld: cannot find -lmingwex
/usr/lib/gcc/x86_64-pc-cygwin/4.9.2/../../../../x86_64-pc-cygwin/bin/ld: cannot find -lmingw32
collect2: error: ld returned 1 exit status

[mattn]

you need to install mingw not cygwin.

[arulrajalivi]

sure pointed it to C:/minggw/bin and getting this error:

github.com/mattn/go-sqlite3

cc1.exe: sorry, unimplemented: 64-bit mode not compiled in

Does this mean mingw-w64 is the only option to build go-sqlite on 64-bit systems?
Can we do something about that?

[mattn]

AFAICS, @arulrajalivi 's compiler doesn't support 64bit.

[cfstras]

The default MinGW builds don't support 64bit, and on cygwin(64), go-sqlite doesn't link.

I use msys2 64 bit. I met the same problem. How to resolve it ?

[mattn]

don't use msys2 to build go app. msys2 rewrite $PATH with slash separators.

I am using this version of gcc (64 bit) and go get's run fine:

[Yggdrasill1989]

I installed TDM-GCC (64 bit), and I get some error:

fatal: unable to access 'https://github.com/mattn/go-sqlite3/': error setting certificate verify locations:

@Yggdrasill1989 it's not issue of go-sqlite3.

@Yggdrasill1989: Big firewall ? ultrasurf is your friend !

[Yggdrasill1989]

Thanks for your answers.
There's some problem about link to https, and I change to ssh link clone the project, it worked.

Installing 64-bit TDM-GCC worked for me. Cygwin was unable to locate 64-bit gcc even though I had chosen it to be installed during cygwin installation.
