Building C library on MacOs Ventura 13.2 #5

Open PeterHartfield opened 1 year ago

PeterHartfield commented 1 year ago

I have a Raspberry Pi 4 8GB running 32 bit Buster OS (clean install), linux kernel 5.15.84-v7l+, Binutils for Raspbian 2.35.2, GLIBC 2.31 - all steps on the Pi completed successfully.

The MacBook Pro is on Ventura 13.2 (latest release). I have overcome a few problems along the way, but now I'm stuck at the "ct-ng build" stage with the following error "Building C library"...

I have been through the known issues and upped the file descriptors to 1024, which made no difference. Tried installing glibc and dependencies but keeps saying I need Linux :-( (I'm on MacOS because that's what these instructions are for - right?).

Any suggestions would be most appreciated to get me to the next step, or even better, completion :-)

Thanks in advance, Peter

Hello, I did not update this tutorial from some time. I will restore my MacBook and I will follow this tutorial to found new/old misstakes. Thanks.

Thanks, I would appreciate any help. In the meantime, I have built Qt 6.4.2 and QtCreator 9.0.1 on the Raspberry Pi - no mean feat, took about 12 hrs to build. Now I can at least clone the source from GitHub and build the app on the Pi. Cheers, Peter

giridhar123 commented 1 year ago

Yes but if the app starts to be complex, compile and test start to be slow too :)

I have similar problem with glibc 2.35. Try editing the crosstool-ng configuration and set a lower GLIBC version. Then build again.

Thanks for the suggestion, I'll give it a go on the weekend and let you know the results.

I had issues building crosstool-ng on the mac so installed it with brew (1.25.0). Now having issues building the toolchain as its expecting to get zlib 1.2.12 but I have 1.2.13 installed. My glibc version is 2.31 - the latest version 2.35 doesn't appear to be supported on M1 MACs (intel 64 bit linux only). So now I'm not even getting as far as I did last time :-(

Hello @PeterHartfield I got new about you problem. You can fix that problem in 2 ways. Editing the zlib version manually inside the config file (because the link to download the 1.2.12 version is outdated) and change it to 1.2.13, or, you can build the master branch of the crosstool-ng repository. BTW I recompiled everything (Qt and the cross tools) using GCC 13 and Qt 6.5.1. I think that this time I will build a clone of the SD card of the Raspberry Pi and I will upload all the compile cross tool to avoid this kind of problems. This time it has been hard for me also.
