So basically: when we open the .so file, we define some symbols, and it appears that if we load something else, with the same symbols, under the same thread we cause some funky behaviour - like calling function a wownero function MONERO_Wallet_address() resulting in a monero address being generated. Needless to say, this is undesired, and a blocker for https://github.com/cypherstack/stack_wallet/pull/818 I'm afraid that this may not solve all of our issues (but will solve some significant roadblocks), because of the "genesis block" issue, as output of nm -gDC release/wownero/x86_64-linux-gnu_libwallet2_api_c.so | grep genesis indicate that these functions may share *something* in common across both WOW and XMR libraries. In a case in which this fix won't be sufficient, I think that the way forward would be to close the dynamic libraries, but before we do that I want to check if maybe there is a change to run multiple wallets at once.
wallet2_api.h (but this time C compatible)
Wrapper around wallet2_api.h that can be called using C api.
Building
to "clean" everything:
$ rm -rf monero wownero release
$ git submodule update --init --recursive --force
fix ownership (if you build in docker but clone as a local user)
$ sudo chown $(whoami) . -R
patch codebase
$ ./apply_patches.sh monero
$ ./apply_patches.sh wownero
build monero_c
$ ./build_single.sh monero x86_64-linux-gnu -j$(nproc)
wownero i686-linux-gnu
aarch64-linux-gnu
x86_64-linux-android
i686-linux-android
aarch64-linux-android
arm-linux-androideabi
i686-w64-mingw32
x86_64-w64-mingw32
While building I aim to compile the code at oldest supported release of debian, using default toolchain to ensure that all linux distributions are able to run monero_c libraries, below I present a supported builders for given targets

Libraries on CI are build using the following docker images:
- git.mrcyjanek.net/mrcyjanek/debian:buster
- git.mrcyjanek.net/mrcyjanek/debian:bookworm
It is entirely possible to use upstream debian:buster / debian:bookworm
Contributing
To contribute you can visit git.mrcyjanek.net/mrcyjanek/monero_c and open a PR, alternatively use any other code mirror or send patches directly.
IMPORTANT I don't have time to write better README, please check build_single.sh for build instructions, in general it comes down to running the script.
