If I understand it correctly, cgo should have generated a
_cgo_export.h header with a declaration for your exported function.
Can you please post the generated declaration?

Hello Alexander,
from my understanding, we need to build a GO 32 bits DLL for a C software.
To load this DLL, the C software loads an entry point function called
_RVExtension@12 wich is a decorated/mangle C name/
It seems that cgo doesn't accept to export functions with '@' in name
composition
Or was this it?
#ifdef __cplusplus
extern "C" {
#endif
extern void _RVExtensionVersion(char* p0, size_t p1);
extern void _RVExtensionArgs(char* p0, size_t p1, char* p2, char** p3, int p4);
extern void _RVExtension(char* p0, size_t p1, char* p2);
#ifdef __cplusplus
}
#endif
The 32-bit exports list
Hi everyone,
Thank you all for all your precious pieces of advice. I think I'm slowly
going to have a look at the different possibilities to contribute to the Go
language.
As some of you noticed, I'm kind of more motivated when I think about
helping in the go codebase than other sorts of tasks (th
/* Code generated by cmd/cgo; DO NOT EDIT. */
/* package _/F_/Git/returnHWID-Arma */
#line 1 "cgo-builtin-export-prolog"
#include /* for ptrdiff_t below */
#ifndef GO_CGO_EXPORT_PROLOGUE_H
#define GO_CGO_EXPORT_PROLOGUE_H
#ifndef GO_CGO_GOSTRING_TYPEDEF
typedef struct { const char *p; ptrdif
Ok. Thanks.
What's the output of dumpbin.exe /EXPORTS /path/to/slib.dll showing
the listing of your exported functions?

i don't know why it so much verbose perhaps i don't use the good
compilation flag .
Here another dump of a 32 bit dll extension with the same entry point but

I am using cgo in this project where I need the following given .so files.

sudo does not preserve environment variables for security reasons, run:
sudo echo $LD_LIBRARY_PATH
You'll likely see that it's empty, unless you have a global system one set.

Hi,
i think sudo kills the LD_LIBRARY_PATH variable.
But this is configurable, try something like:
Defaultsenv_keep += “LD_LIBRARY_PATH"
in /etc/sudoers and / or consult the sudo man page.
Best regards,
Michael

You could try:
sudo -E bash -c 'echo $LD_LIBRARY_PATH'
The -E is --preserve-env

HI Michael,
Looks like it is still not preserving the env variable:
nsaboo@ubuntu:~/Documents/goworkspace/src/poc$ export
LD_LIBRARY_PATH=/usr/local/lib/syslog-ng
nsaboo@ubuntu:~/Documents/goworkspace/src/poc$ sudo -E bash -c 'echo
$LD_LIBRARY_PATH'

I have been trying to use both Tarmigan's and Jacob's packages on Windows
and Linux. For basic serial reading they both seem to work just fine.
However, they both seem to break with higher baud rate and continues
streaming of data. In my case I was streaming sensor data at baud rate
921600, th

That means your "sudo" configuration doesn't allow the use of the `-E`
flag; at least in that specific use case. Alternatively, your system
doesn't preserve the value of `LD_LIBRARY_PATH` when the shell is invoked
via `sudo -E` because the shell's startup scripts clobber that var.
I hope you recog
