I followed the instructions on the page except that I used the amd64-64-24k-pic implementation so that I'd get the PIC fixes. It looks like there's an instance that was missed.

problem

Project consists of 3 subprojects: EDIMPL, HASH, RANDOM. Each of subprojects can have many implementations. The task is to produce single SHARED library, which is a result of merging of 3 subprojects.

requirements

We consider two clients of this repository:

"build only what you need" client -- this client typically needs to produce single libed25519.so, which consists of selected implementations. Nothing else should be built.
"CI" client -- this client typically needs to build all possible combinations of libraries and execute tests against them, collect coverage of all execution paths and execute static / dynamic analyzers.

We can't just define all targets and add them to all target (usual make), because it is likely that some combinations will work on client (1) and some will not (example is EDIMPL=amd64-64-24k-pic on MAC, it will not work). make install for such client will fail.

From the other side, client (2) can typically build all targets or almost all targets -- it has all dependencies (such as openssl) and it has proper architecture (amd64).

solutions

solution 1 (https://github.com/hyperledger/iroha-ed25519/releases/tag/1.1.0)

Define every implementation as OBJECT library and include OBJECT library in every dependent target. Client specifies EDIMPL, HASH, RANDOM and combination of these libraries is built together in single SHARED ed25519.

Problems:

some implementations depend on other libraries, such as openssl and it is not possible to link anything to OBJECT library, therefore it results in linking error.
to test all combinations in CI (client (2)) we need to write a lot of CI steps. Hard to write them and maintain.
hard to collect coverage

solution 2

Define every implementation as STATIC library.

Problems:

resulting SHARED library will not contain symbols of STATIC libraries.
above problem can be solved with flag -Wl,--whole-archive ${lib1} ${lib2} ${lib3} -Wl,--no-whole-archive. But in this case this error appears:
```
/usr/bin/ld: lib/ed25519/amd64-64-24k/CMakeFiles/amd64-64-24k.dir/fe25519_mul.s.o: relocation R_X86_64_32S against `crypto_sign_ed25519_amd64_64_38' can not be used when making a shared object; recompile with -fPIC		
lib/ed25519/amd64-64-24k/CMakeFiles/amd64-64-24k.dir/fe25519_mul.s.o: error adding symbols: Bad value		
collect2: error: ld returned 1 exit status		
CMakeFiles/ed25519.dir/build.make:211: recipe for target 'libed25519.so.1.2.2' failed
```
even when everything is built with -fPIC.

And above problem again can be solved with something like linker exportmap:
https://github.com/hyperledger/iroha-ed25519/blob/master/src/CMakeLists.txt#L14-L16
https://github.com/hyperledger/iroha-ed25519/blob/master/exportmap

But, exactly this solution is not portable -- only Linux ld can use exportmap.

solution 3

Append all sources to a variable and use them in single ed25519 target as it is done here:
https://github.com/hyperledger/iroha-ed25519/blob/master/src/CMakeLists.txt#L8-L32

Problems:

same problem as with use of --whole-archive.
every test recompiles target from scratch, which increases compilation time.

Compiler overriding

For now cmake overrides the system-defined compiler, would be nice to fix that

Add -Werror in compilation flags
