Hello, This is probably an unusual situation, but I am working on a product that has the following chain of invocation.
C (native shared library libfoo.so) -> Go (c-shared libbar.so) So basically, a native C shared library invokes a -buildmode=c-shared type Go shared library. This interaction works just fine. However, we are augmenting libbar.so (Go shared library) to invoke a Go-style plugin (libplugin.so) using Go's plugin package. The very first attempt of this, failed like this: fatal error: runtime: no plugin module data goroutine 17 [running, locked to thread]: runtime.throw(0xf72b5cc4, 0x1e) /usr/local/go/src/runtime/panic.go:774 +0x70 fp=0xc64d1b48 sp=0xc64d1b34 pc=0xf71bfdd0 plugin.lastmoduleinit(0xc648e5e0, 0x1001, 0x1001, 0xc64823e8, 0x95b9588) /usr/local/go/src/runtime/plugin.go:20 +0xa50 fp=0xc64d1bd4 sp= 0xc64d1b48 pc=0xf71c1420 plugin.open(0xc64a60c0, 0x26, 0x29, 0xc64a6060, 0x2a) /usr/local/go/src/plugin/plugin_dlopen.go:77 +0x388 fp=0xc64d1d2c sp= 0xc64d1bd4 pc=0xf7275ad8 plugin.Open(...) /usr/local/go/src/plugin/plugin.go:32 zero/base/interfaces.glob..func1(0xc64a60c0, 0x29, 0xf72b2610, 0x11, 0x29, 0x0, 0xf719e2e5, 0xf71d958c) /app/base/interfaces/plugin.go:12 +0x2e fp=0xc64d1d68 sp=0xc64d1d2c pc= 0xf7276cbe zero/base.glob..func4(0xf7759c60, 0x21, 0xf7357f80, 0xc64823e0, 0xc64a8445, 0x5, 0xf, 0xe, 0xd, 0xd) /app/base/zl_helper.go:28 +0xb4 fp=0xc64d1d9c sp=0xc64d1d68 pc= 0xf72ac554 main.glob..func10(0xffa1e800, 0x2, 0x2, 0xf7759c60, 0x21, 0xf775ac60, 0x1b, 0x15, 0xc648e5c0, 0x5, ...) /app/dec/dec.go:328 +0x7a fp=0xc64d1dd8 sp=0xc64d1d9c pc=0xf72aeb0a main.glob..func11(0xffa1e800, 0x2, 0x2, 0xf7759c60, 0x21, 0xf775ac60, 0x1b, 0x15, 0xc6496040, 0x5, ...) /app/dec/dec.go:368 +0xa3 fp=0xc64d1e34 sp=0xc64d1dd8 pc=0xf72aee13 main.Decorate(0xffa1e800, 0x2, 0x2, 0xf7759c60, 0x21, 0xf775ac60, 0x1b, 0x15 , 0xc6436000) /app/dec/dec.go:98 +0x1f3 fp=0xc64d1eac sp=0xc64d1e34 pc=0xf72ad0b3 main._cgoexpwrap_079f3b2ec7da_Decorate(0xffa1e800, 0x2, 0x2, 0xf7759c60, 0x21, 0xf775ac60, 0x1b, 0x15, 0x0) _cgo_gotypes.go:79 +0x95 fp=0xc64d1ef4 sp=0xc64d1eac pc=0xf72ace15 runtime.call64(0x0, 0xffa1e72c, 0xffa1e79c, 0x24, 0x0) /usr/local/go/src/runtime/asm_386.s:571 +0x31 fp=0xc64d1f38 sp= 0xc64d1ef4 pc=0xf71e9ad1 runtime.cgocallbackg1(0x0) /usr/local/go/src/runtime/cgocall.go:314 +0x162 fp=0xc64d1fb0 sp= 0xc64d1f38 pc=0xf71966f2 runtime.cgocallbackg(0x0) /usr/local/go/src/runtime/cgocall.go:191 +0x9d fp=0xc64d1fe0 sp= 0xc64d1fb0 pc=0xf719650d runtime.cgocallback_gofunc(0x0, 0x0, 0x0, 0x0) /usr/local/go/src/runtime/asm_386.s:810 +0x79 fp=0xc64d1ff0 sp= 0xc64d1fe0 pc=0xf71eab79 runtime.goexit() /usr/local/go/src/runtime/asm_386.s:1325 +0x1 fp=0xc64d1ff4 sp= 0xc64d1ff0 pc=0xf71eb081 Aborted What is the error indicative of? Is invoking go plugin from go shared library supported? I know Go plugins have a few restrictions. I have verified that all the above libraries are built on the same machine with the same gcc/go toolkit. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
