I think that the above contradicts the following. > In the debian distribution also installed on the machine, > there is a separate lib64 directory, and it is enough to pass the flag "-mabi= > 64" to gcc. Is it supported in Debian? Also, what about compatibility? Are there any downsides? "But an ABI can be chosen explicitly to make GMP compatible with other libraries, or particular application requirements." [1] I'll give it a try if you provide detailed instructions.
