Build app still require gcc

[kpvt001]

I found that

However, if you install go-sqlite3 with go install github.com/mattn/go-sqlite3, you don't need gcc to build your app anymore.

in Readme.md

But, after installed go-sqlite3 and go-sqlite3.a existed, it still require gcc when I building the app.

os: windows 10 x64 pro

[mattn]

Could you please show me go build -x?

[kpvt001]

F:\gopath\src\github.com\mattn\go-sqlite3>go build -x
WORK=C:\Users\User\AppData\Local\Temp\go-build633774530

[kpvt001]

go build and go install show nothing, I think they run successfully.

[mattn]

I don't still what you mean. What do you mean it still require gcc when I building the app?

[kpvt001]

When I build the app, it shows

F:\gopath\src\project>go build
# project
C:\Go\pkg\tool\windows_amd64\link.exe: running gcc failed: exec: "gcc": executable file not found in %PATH%

But i successfully installed go-sqlite3 by go install, and go-sqlite3.a also created in pkg.

After installed, I uninstalled TDM-GCC.

Then, please show me go build -x and go env

[mattn]

please try to install go-sqlite3 with go install -buildmode=c-archive

[kpvt001]

failed

F:\gopath\src\github.com\mattn\go-sqlite3>go install -buildmode=c-archive
-buildmode=c-archive requires exactly one main package

[kpvt001]

In my another vm installing TDM-GCC, can build app successfully, in this one cannot,

Btw, in this vm, I just copied TDM-GCC files instead of installing, run mingwvars.bat to set vars before building go-sqlite3. The go-sqlite3.a built in 2 vms are the same.

[mattn]

What do you get with go build -ldflags="-linkmode=internal -extld=none" -x ?

[kpvt001]

app or go-sqlite3?

[mattn]

please try on app

[kpvt001]

Built successfully, get the exe.

Whether the situation is common or not?

[mattn]

There are some conditions why the build fail with this error.

[kpvt001]

What can I offer?

[mattn]

Sorry, I don't still clearly understand how to fix this issue with common way.

[kpvt001]

I mean what can i do for you about the issue

[mattn]

This is enoguh since I got one of the resolved results. So if you solved issue, please close this.

[kpvt001]

I think 'go build -ldflags="-linkmode=internal -extld=none" -x' could be added into the readme :)
