[BUG] - Missing ltos

[tsschepens]

Describe the bug
'Make' and 'sudo make install' went well, but for 'make unit-test', I got :
'/sbin/ld: cannot find -ltos: No such file or directory'
Which led to :
ERROR: Failed to execute command: 'gcc -L/usr/local/lib /tmp/holyc-asm.s -ltos -lpthread -lc -lm -o test-runner'
make[4]: *** [CMakeFiles/unit-test.dir/build.make:72: CMakeFiles/unit-test] Error 1
make[3]: *** [CMakeFiles/Makefile2:120: CMakeFiles/unit-test.dir/all] Error 2
make[2]: *** [CMakeFiles/Makefile2:127: CMakeFiles/unit-test.dir/rule] Error 2
make[1]: *** [Makefile:182: unit-test] Error 2

I also tried to compile a simple test.HC file and I got :
hcc test.HC
/sbin/ld: cannot find -ltos: No such file or directory
collect2: error: ld returned 1 exit status
ERROR: Failed to execute command: 'gcc -L/home/purple/.local/lib /tmp/holyc-asm.s -ltos -lpthread -lc -lm -o a.out'

To Reproduce

1. git clone https://github.com/Jamesbarford/holyc-lang
2. make && sudo make install && make unit-test

Expected behavior
A successfull execution of the test and the working Holy-C compiler

Compiler version
hcc beta-v0.0.10

Desktop:

• OS: Arch Linux x86_64
• Kernel: Linux 6.16.8-arch3-1

I don't know is there an official solution but I've faced the same issue and made a script for making clean libtos. You can look it in pull requests and generate missing file.

[Jamesbarford]

Thanks for having a look at this, @Cn8001 are you also on Arch Linux?

[Cn8001]

Hello @Jamesbarford , although I usually deal with Debian-based systems, I like Arch Linux but I haven't had the opportunity to use it much.

[Jamesbarford]

Are you also seeing this problem?

[Cn8001]

Yes, -ltos is trying to link with libtos and libtos is not generated even though there is an implementation for that. (In tos.HH, there is a note saying that this header is not required, but I didn't see another ltos generator.). So a build_libtos.sh script also modified CMAke is made in order to generate libtos without double referencing common functions like _MEMSET accross multiple object files.

I don't really know make/cmake. What is required to build libtos ourself ?

[Cn8001]

@tsschepens I'll try to give step by step guide, I haven't tested it in Arch but this is how I solved it in Ubuntu and bash should be the same.

1. Clone the repository and go to the ./src/holyc-lib
2. Open set.HC and add #include "./strings.HC" on top of the file.
3. Go to the base path again and run make && make install, give root privileges if needed.
4. Get build_libtos.sh script from pull request or my fork and save it inside src/holyc-lib directory (this one is important)
5. Add chmod +x if needed
6. Run the script, it will compile HC libraries and create a libtos.a file
7. Place it inside shared lib destination (/usr/local/lib for Ubuntu)

[Jamesbarford]

This should now be fixed with; #193

Essentially a mis-compilation caused the lib file to not be created, the error was swallowed and thus the install was silently failing.

Please pull down the latest code from main. I'd apprecaite if you can let me know if that works

[Jamesbarford]

A successful install should look something like;

sudo make install

Then;

/Library/Developer/CommandLineTools/usr/bin/make -C ./build install
