Have problems building the library

Question

Have problems building the library

rempas opened this issue a year ago · comments

I'm under Arch Linux (btw) and I have downloaded the source code from the download page.

When I'm trying to run cmake using the following configuration: cmake .. -DCMAKE_BUILD_TYPE=Release \ -DCMAKE_INSTALL_PREFIX=/home/rempas/.local \

I do get the following error:

Should I try with the "git" version?

You can try git master, but I don't think it would be any different.

This log is btw not sufficient to diagnose the error - full log would be nice (without cmake cache) and the C++ compiler you are using as well (and target architecture).

Alright! I'm a n00b with CMake (have never personally use it), could you help me a little bit about how to get the information you need? I was not able to find the log. For the C++ compiler, I haven't chooses anything specific. If CMake uses the "c++" link, it is linked to GCC in my system. But Clang is installed as well so I don't know if it prioritizes that instead.

Which commands to execute starting from the "build" directory (or from Blend2d's source if you prefer, just let me know)?

Petr Kobalicek · Answer 3 · Wed Jul 19 2023 01:49:42 GMT+0800 (China Standard Time)

I would just delete the build directory completely and use:

cd tools
./configure-makefiles.sh

and then print the output here.

Also cmake --version would be great, but it should be >= 3.8 already if it passes the version check.

Cmake should detect the compiler and print things it detects, that would definitely help.

rempas · Answer 4 · Wed Jul 19 2023 01:56:58 GMT+0800 (China Standard Time)

The output of cmake --version: cmake version 3.26.4

I hope you mean the output of ./configure-makefile.sh because, oh boy, it's big! Here it is:

It is weird however that it says that it does the "debug" configuration in the beginning but in the end, it says that the files have been written to: /home/rempas/Projects/Programming/blend2d/build/Release. Check that "release" in the end. Weird...

Petr Kobalicek · Answer 6 · Wed Jul 19 2023 02:26:38 GMT+0800 (China Standard Time)

It does two configurations - Debug and Release. Basically it's used mostly for development to configure the project quickly.

The output seems good, there are no errors, so I'm not really sure what was the problem initially. Does it build?

cd build/Release
make

rempas · Answer 7 · Wed Jul 19 2023 03:18:03 GMT+0800 (China Standard Time)

Sure! It compiles well! We're done with that, now what about the configuration options? I want to change the prefix specifically.

Petr Kobalicek · Answer 8 · Wed Jul 19 2023 03:52:14 GMT+0800 (China Standard Time)

I just tried, and it works without a problem. Try something like this:

# in blend2d dir:
mkdir build_prefix
cd build_prefix
mkdir $HOME/your_install_target
cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=$HOME/your_install_target
make 
make install

rempas · Answer 9 · Wed Jul 19 2023 03:57:20 GMT+0800 (China Standard Time)

Haha, nope! It will not do me the favor! This is how I tried to do it in the beginning and got the error. Are you on Linux as well? Maybe a platform problem...

Petr Kobalicek · Answer 10 · Wed Jul 19 2023 04:03:09 GMT+0800 (China Standard Time)

I would try to avoid the \ slashes initially. And yeah, I'm on Linux, and this is a pretty basic feature, so hard to tell why it doesn't work in your case

rempas · Answer 11 · Wed Jul 19 2023 04:05:26 GMT+0800 (China Standard Time)

I did avoid them. It seems to me that there is something going on with Cmake based on the error message. The worse thing is that it seems that you will probably not be able to help...

rempas · Answer 12 · Wed Jul 19 2023 04:05:44 GMT+0800 (China Standard Time)

Well, I'm gonna try the git version!

Petr Kobalicek · Answer 13 · Wed Jul 19 2023 04:06:01 GMT+0800 (China Standard Time)

What is your cmake --version?

rempas · Answer 14 · Wed Jul 19 2023 04:08:08 GMT+0800 (China Standard Time)

3.26.4

But wait, there is more! So, I downloaded the git version and tried with it! Now, I do get a different problem error.

Does this say anything to you? I did used EXACTLY the Cmake comment you gave me. And, why does it have a different error message now? Aaaaah, so many questions....

rempas · Answer 16 · Wed Jul 19 2023 04:14:58 GMT+0800 (China Standard Time)

Wait a minute! If it searches for a file called "/CMakeLists.txt", then it is an absolute path! This may explain why it cannot find the file.

Further more, who chooses where the "CMakeLists.txt" is located? Is there an option to override its location?

Petr Kobalicek · Answer 17 · Wed Jul 19 2023 04:43:40 GMT+0800 (China Standard Time)

Blend2D git repository doesn't bundle asmjit library, only releases do. For convenience, Blend2D would look in either parent directory or 3rdparty directory for asmjit - if it cannot find it, it would error.

BTW this is documented here in a section called "Building From Source":

https://blend2d.com/doc/build-instructions.html

rempas · Answer 18 · Wed Jul 19 2023 04:55:30 GMT+0800 (China Standard Time)

Oh!!! The version I downloaded had it inside "tools". That's why there is a different error message now, it makes absolute sense! If only I knew about that earlier, I just wasted your time over nothing...

But still, the version in the download page doesn't work so, I suppose a note would be nice so people don't waste your time for the same thing in the future.

So, I confirm that everything works! Thank you for your time and have a great day or night!

Petr Kobalicek · Answer 19 · Wed Jul 19 2023 05:16:58 GMT+0800 (China Standard Time)

Glad it works, there will be a new version soon :)

rempas · Answer 20 · Wed Jul 19 2023 13:35:27 GMT+0800 (China Standard Time)

Nice! And thank you for having a C API, as I'm planning to create my own programming language and this will come in handy to create binding for it!
