How to properly build these 2 static libraries and use them for my code? No matter what I try I get some compilation errors in my test program. I followed the official steps, but it didn't work and internet didn't give me an answer...
Here is what I do to build tomsfastmath:
git clone https://github.com/libtom/tomsfastmath.git
cd tomsfastmath
sudo make install
And here is what I do to install libtomcrypt:
git clone https://github.com/libtom/libtomcrypt.git
cd libtomcrypt
sudo make CFLAGS="-DUSE_TFM -DTFM_DESC" EXTRALIBS="-ltfm" install
I tried only sudo make install, but it didn't seem to solve my issue. I only got undefinded reference to `tfm_desc' in that case, instead of the current error...
And here is how I compile my code:
g++ "%f" -o "%e" -pipe -fwrapv -fno-plt -fno-semantic-interposition -std=c++20 -mcmodel=large -march=x86-64 -mtune=generic -Wshadow -Wno-unused-result -Wall -O3 -L /usr/lib -Wl,--as-needed -lm -lz -lpthread -lutil -ldl -lrt -lcrypt -lgcrypt -Wl,-Bstatic -ltfm -ltomcrypt -Wl,-Bdynamic
It's my full g++ command, I provide it whole because I don't understand this command fully so you might catch a silly mistake...
This is essentially my whole code (without some empty functions):
#include <cstdio>
#include <cstdlib>
#include <cstring>
#define TFM_DESC
#include <tomcrypt.h>
int main(){
ltc_mp=tfm_desc;
}
And this is the error I am getting:
g++ "crypt.cpp" -o "crypt" -pipe -fwrapv -fno-plt -fno-semantic-interposition -std=c++20 -mcmodel=large -march=x86-64 -mtune=generic -Wshadow -Wno-unused-result -Wall -O3 -L /usr/lib -Wl,--as-needed -lm -lz -lpthread -lutil -ldl -lrt -lcrypt -lgcrypt -Wl,-Bstatic -ltfm -ltomcrypt -Wl,-Bdynamic (in directory: /home/korsic/Documents/c++__projekti/traktor)

Compilation failed.
I don't know what useful I can say more, I have been trying whatever came to my mind which is not much, I could only follow the official git... I just want my code to compile normally, I am trying to compile an example RSA encrypt code that is provided in the official manual https://github.com/libtom/libtomcrypt/releases/download/v1.18.2/crypt-1.18.2.pdf on page 96. How do I do it properly?
