[Mingw-users] How to call NetUserAdd from netapi32 library? linker is failing on me...

[Rui L. <rg...@ru...>]

Hello,

I'm trying to use the NetUserAdd function from netapi32 library, but
its failing on me:

gcc -shared -oservice-setup-helper.dll -lnetapi32 service-setup-helper.c
C:\Users\RUILOP~1\AppData\Local\Temp\ccHqnS1l.o:service-setup-helper.c:(.text+0x5f):
undefined reference to `NetUserAdd@16'
collect2: ld returned 1 exit status


Note that objdump only reports _NetUserAdd@16 (with leading underscore):

objdump -t /c/Dev/MinGW/lib/libnetapi32.a | grep UserAdd
[  7](sec  1)(fl 0x00)(ty   0)(scl   2) (nx 0) 0x00000000 _NetUserAdd@16
[  8](sec  5)(fl 0x00)(ty   0)(scl   2) (nx 0) 0x00000000 __imp__NetUserAdd@16


What is going on? How do I use NetUserAdd?

TIA!

Best Regards,
Rui Lopes

    DWORD paramError;
    NET_API_STATUS status = NetUserAdd(NULL, 1, (PBYTE)&userInfo, &paramError);

    return status;
