Hi,
Buildroot and OpenADK have samples to create a Linux system to be
bootup in Qemu system emulation for microblaze architecture.
With gcc 6.3 and 7.1 the samples are not working anymore,
because the Linux system userland does not boot.
Qemu 2.9.0:
Kernel panic - not syncing: Attempted to kill init!
exitcode=0x0000000b
(with glibc, musl and uClibc-ng toolchains)
I bisected gcc source code and found the bad commit:
6dcad60c0ef48af584395a40feeb256fb82986a8
When reverting the change, gcc 6.3 and 7.1 produces working
Linux rootfs again.
What can we do about it?
best regards
Waldemar
Hello,
Would you consider making a GitHub account and host the code there? It is just that it would be so much easier to send and discuss patches that way instead of with a mailing list. I used buildroot before on linux and never took the time to send patches because of the procedure. Now I am on macOS so I switched to openADK which works nicely! (especially the update-patches is nice). Would you maybe be open to that?
FYI, Here is a list of issues I encountered:
- raspberry pi 1 model B+ is my board. The kernel did not compile. Then I added some needed config values like from the official defconfig, and then it compiled. But it did not boot my system. Then I selected to use the supplied defconfig from the kernel, and now it boots and works.
- I had some issues compiling glib-host on a latest generation macbook with Xcode 8.3.2, it seems I had an extra uuid.h file in the include directory, which made compiling fail because it was not using the one from my system. Then it did not link to the AppKit framework in the end, which I fixed with setting the HOST_LDFLAGS in the package
- qtbase: seems I needed to apply the patch in attachment to make it compile with Qt 5.7.0, which is taken from 5.9. Also, the detection of the xcodebuild needed to be fixed.
Best regards
Tom,
