Symbol lookup error #80

Closed matilote closed 3 years ago

matilote commented 4 years ago

When trying to use shared library libmclbn256.so & libmclbn384_256 I got the symbol lookup error. Do I miss something during the build?

The active test run was aborted. Reason: Test host process crashed : /usr/share/dotnet/dotnet: symbol lookup error: /root/libmclbn384_256.so: undefined symbol: _ZN3mcl2fp2Op4initERK10__gmp_exprIA1_12__mpz_structS4_EmiNS0_4ModeEm

Build

git clone git://github.com/herumi/mcl
cd mcl
make -j4

ldd libmclbn256.so output: image

When building with cmake the library appears to work only on my local machine.

It seems the function of GMP. So could you install libgmp or build a library without gmp.

No luck without GMP:

The active test run was aborted. Reason: Test host process crashed : /usr/share/dotnet/dotnet: symbol lookup error: libmclbn384_256.so: undefined symbol: _ZN3mcl2fp2Op4initERKNS_5VintTINS_4vint6BufferImEEEEmiNS0_4ModeEm

It now complains about Vint. I wonder why does the cmaked shared lib work locally. When exported to some VM it crashes if mcl is not installed.

What OS and compiler do you use? On Ubuntu 18.04.4 + gcc 7.5.0

Btw. dll built on Windows machine works without any issues.
