Hi, Maybe someone can help me.
I managed to install libobjc2 on Ubuntu 22.04 with: sudo apt install cmake git clone https://github.com/gnustep/libobjc2.git cd libobjc2 git submodule init && git submodule update mkdir Build && cd Build cmake .. -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ make -j8 sudo -E make install sudo ldconfig And I am trying to compile and run a very simple application: #include <stdio.h> int main() { @autoreleasepool { printf("Hola món\n"); } return 0; } But when I call: clang main.m -fobjc-runtime=gnustep-2.0 -o main && ./main I get the next error: /usr/bin/ld: /tmp/main-f8c82f.o: in function `main': main.m:(.text+0x18): undefined reference to `objc_autoreleasePoolPush' /usr/bin/ld: main.m:(.text+0x30): undefined reference to `objc_autoreleasePoolPop' /usr/bin/ld: /tmp/main-f8c82f.o: in function `.objcv2_load_function': main.m:(.text..objcv2_load_function[.objcv2_load_function]+0xc): undefined reference to `__objc_load' clang: error: linker command failed with exit code 1 (use -v to see invocation) Thanks, Albert
