• for more details: https://blog.yat1ma30.com/posts/call-golang-function-from-easylanguage/

Env

• Windows 10 64-bit
• TradeStation 9.5
• gcc 5.1.0 (tdm-1)
  • http://tdm-gcc.tdragon.net/download
  • append C:\<your-folder>\TDM-GCC-32\bin\ to path
• go version go1.12.1 windows/amd64
• Cmder (whatever)

What you can do with this

You can call CalcDouble function (Go),

//export CalcDouble
func CalcDouble(x float64) float64 {
	return 2 * x
}

from EasyLanguage.

using elsystem;

external: "yat1ma30\example.dll", double, "CalcDouble", double;

once begin
  ClearPrintLog;
  Print(CalcDouble(2.5)); // 5
end;

Usage

Prepare 32 bit Go first.

set GOARCH=386
set goroot_bootstrap=%goroot%
cd %goroot%\src
make.bat --no-clean

Create a static library. The following command exports example.a and example.h.

set GOARCH=386
set CGO_ENABLED=1
set CC=gcc
go build -o libexample.a -buildmode=c-archive main.go

Create a dll using the C wrapper.

gcc -o example.dll example.def -mdll example.cpp -L. -lexample -lwinmm -lws2_32 -lntdll

Copy the dll file into TradeStation folder.

e.g. C:\Program Files (x86)\TradeStation 9.5\Program\yat1ma30\example.dll

Then call the function from EasyLanguage.

using elsystem;

external: "yat1ma30\example.dll", double, "CalcDouble", double;

once begin
  ClearPrintLog;
  Print(CalcDouble(2.5)); // 5
end;
