linker issue under linux with static libs

danielkuettner · 2021-04-25 19:00:32

I'm using mORMot but for OpenSslVerify I've used mormon.crypt.openssl from mORMot2 with actual static libs from get_latest_static.sh.
After compiling following error comes from linker:

mORMot2/test/build_fpc.sh compiles and links without errors.

try to search a linker path (LD_LIBRARY_PATH) for sha512-x64sse4.* - I think you have an old version somethere

danielkuettner · 2021-04-26 07:36:34

LD_LIBRARY_PATH was empty. I've set it to /home/daniel/mORMot2/static/x86_64-linux where sha512-x64sse4.o and others are located, but same errors.
My guess is that it comes from mixing mORMot with mORMot2. I've also tried to replace SynCrypto but its also used in mORMot.pas.

There seems to be a declaration of a variable or function in a header file, which is included in more than one *.c file.

mORMot 1 and mORMot 2 statics are not compatible.

Here is what I usually do:
For mORMot 1, I put the static folders hard-coded in each project option;
For mORMot 2, I use the Lazarus package.

Thanks @mpv and @ab.

I had to disable

{.$L static/x86_64-linux/sha512-x64sse4.o}
{.$L static/x86_64-linux/crc32c64.o}

in SynCrypto.pas.

Now the linker is happy again

It is weird, I don't have any such problem here...

danielkuettner · 2021-04-26 09:25:31

And you are also mixing mORMot and mORMot2?

ab · 2021-04-26 10:36:07

Oh no, you should never mix both of them in the same project!
There would be plenty of problems for sure - starting indeed with static linking issues.

You also shouldn't drink alcohol. But sometimes it's worth doing it.

Is it any wonder then if you wake up hung-over?
