Here are my compiler logs I don't quite understand what to do

$ emmake make CFLAGS="-fstack-protector-strong" LDFLAGS="-fstack-protector-strong"

  • I do not know the answer but this does not look correct for a linker flag: **LDFLAGS="-fstack-protector-strong"** – John Hanley Jun 04 '22 at 21:44
  • I try without it, but the result is the same – Ryufuz Jun 08 '22 at 14:51
  • I did not say remove it, I provided a suggestion that it is incorrect. Lookup the correct linker options/flags. – John Hanley Jun 08 '22 at 16:44
  • Oh, very thanlk you for answering. I solved a problem but not clearly understand on which step it was fixed. Now i will write "what i was doing" in the answer... – Ryufuz Jun 08 '22 at 23:07

The problem is solved, but I did not track at what step it was done, since I walked in circles many times.

From the moment it didn't work for me, I did:

-installed bison and gawk

sudo apt install bison gawk

-copied the "c++" folder from the Include folder to the /usr/share/emscripten/cache/sysroot/include directory.

  • switched to providing python, with the commands:

    python3 '/usr/share/emscripten/emconfigure.py' ./configure --prefix="$(pwd)/install"

    python3 '/usr/share/emscripten/emmake.py' make clean

    python3 '/usr/share/emscripten/emmake.py' make

  • when code errors occur, set

    sudo apt install python3-pysodium

  • after I solved a couple of compilation errors (from a very long list of errors) and corrected by type in terminal:

    emcc -Wall -Wno-error -Wextra -Wno-unused-function -Wmissing-prototypes -Wstrict-prototypes -x c++ -g -O2 -lm -ldl -Wall -Wpointer-arith -finline-functions -ffast-math -DED25519_donna -fPIE -DSTATISTICS -DPASSPHRASE -DVERSION='"unknown"' -D'CRYPTO_NAMESPACETOP=crypto_sign_ed25519_donna' -D'_CRYPTO_NAMESPACETOP=crypto_sign_ed25519_donna' -D'CRYPTO_NAMESPACE(name)=crypto_sign_ed25519_donna##name' -D'_CRYPTO_NAMESPACE(name)=crypto_sign_ed25519_donna ##name' -c -o main.c.o.tmp main.c && mv main.c.o.tmp main.c.o

and then finished compiling

 python3 '/usr/share/emscripten/emmake.py' make
