So here is some interest in the musl versions 😄 I'd need them for Alpine Linux

Is there any reason that libpthread_nonshared.a is missing?

Hi

i am trying to build using CMAKE and toolchain from your repo.
Im having raspberry pi 1 and according to this page https://www.valvers.com/open-software/raspberry-pi/bare-metal-programming-in-c-part-1/, following flags I set:
-march=armv6zk -mcpu=arm1176jzf-s -mfpu=vfp -mfloat-abi=hard

Here is the ouptup of build process

Make Error at /Applications/CMake.app/Contents/share/cmake-3.23/Modules/CMakeTestCXXCompiler.cmake:62 (message):
The C++ compiler

"/Users/dro/Development/arm/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-g++"

is not able to compile a simple test program.

It fails with the following output:

Hey!

I hope you can help me. I have a new M1 Mac and I'm still trying to get all my Raspberry Pi toolchains working again.
Specifically, I'm trying to compile Qt 5.15.2 for Raspberry Pi zero using your toolchain. In the first step the toolchain is tested, which leads directly to an error.

The following linker command executed by ./configure of Qt fails...

/Users/friedemannmetzger/rpi-zero-new/arm-unknown-linux-gnueabihf/bin/arm-unknown-linux-gnueabihf-g++ -mfloat-abi=hard --sysroot=/Users/friedemannmetzger/rpi-zero-new/sysroot -Wl,-O1 -Wl,-rpath-link,/Users/friedemannmetzger/rpi-zero-new/sysroot/opt/vc/lib -Wl,-rpath-link,/Users/friedemannmetzger/rpi-zero-new/sysroot/usr/lib/arm-unknown-linux-gnueabihf -Wl,-rpath-link,/Users/friedemannmetzger/rpi-zero-new/sysroot/lib/arm-unknown-linux-gnueabihf -o verifyspec verifyspec.o

It can't find these files:

/Users/friedemannmetzger/rpi-zero-new/arm-unknown-linux-gnueabihf/bin/../lib/gcc/arm-unknown-linux-gnueabihf/8.3.0/../../../../arm-unknown-linux-gnueabihf/bin/ld.bfd: cannot find crt1.o: No such file or directory
/Users/friedemannmetzger/rpi-zero-new/arm-unknown-linux-gnueabihf/bin/../lib/gcc/arm-unknown-linux-gnueabihf/8.3.0/../../../../arm-unknown-linux-gnueabihf/bin/ld.bfd: cannot find crti.o: No such file or directory

Basically the files are shipped in the sysroot folder. But how do I teach the linker to find and take them?
All attempts with LIBRARY_PATH, LD_LIBRARY_PATH, -I etc.. failed until now. Do you have any idea?

My system:
macOS 12.2.1, M1 Pro

Thank you very much in advance!

Currently, hardfloat is not supported for ArmV7, but is for ArmV8, but the RPI0-W supports V7-hard float. Is it possible to get this supported?

The readme needs some instructions on how to sign the binaries so that they will run on macOS Catalina and later. I used this:

find <install directory> -executable | xargs -n1 sudo codesign --force --deep --sign -

First off THANK YOU, this repo is extremely helpful.

Trying to build my own version of them, as I need a few tweaks, but running into some issues on the bison step of ct-ng.

Wondering if the machine you originally created these with was Intel or M1.

i use the macos big sur and crosstool-ng 1.24.0 build the arm-unknow-linux-gnueabi ,it if faild. can you set you .config to me ? i need build the kernel 4.19

I might be wrong nut I tried compiling c++ under linux to generate a macos library but i cant make gcc genarate Mach-O and After a lot of research this repo is my last hope, can you help me?
Also, really importand, does osx supports arm, ins't just 64 - bit?

Can you use an automated system to push new builds out frequently?

When I'm using this in CLion and cmake, it occurred below.

/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/sys/cdefs.h:784:2: error: #error Unsupported architecture

How can I use this compiler... please.. I need this..

That would be great to automatically build a C/C++ project using cmake and your toolchains.
