"Compilation Error: Missing limits.h Header in Cross-Compilation for GStreamer HelloWorld Example"

[SullyNiu]

Description:

When attempting to compile a GStreamer "Hello World" example (basic-tutorial-1.c) using the cross-compiler toolchain on STM32MP1 with OpenSTLinux, a fatal error occurs indicating that the limits.h header file is missing.

https://gstreamer.freedesktop.org/documentation/tutorials/basic/hello-world.html?gi-language=c

 

Steps to Reproduce:

1. Source the environment setup script:

   source /opt/st/stm32mp1/5.0.3-openstlinux-6.6-yocto-scarthgap-mpu-v24.11.06/environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi

2. Check the cross-compiler:

   echo $CC

   arm-ostl-linux-gnueabi-gcc -mthumb -mfpu=neon-vfpv4 -mfloat-abi=hard -mcpu=cortex-a7 -D_TIME_BITS=64 -D_FILE_OFFSET_BITS=64 --sysroot=/opt/st/stm32mp1/5.0.3-openstlinux-6.6-yocto-scarthgap-mpu-v24.11.06/sysroots/cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi

3. Attempt to compile the program:

   arm-ostl-linux-gnueabi-gcc -Wall basic-tutorial-1.c -o helloworld $(pkg-config --cflags --libs gstreamer-1.0)

Error Message:

/opt/st/stm32mp1/5.0.3-openstlinux-6.6-yocto-scarthgap-mpu-v24.11.06/sysroots/x86_64-ostl_sdk-linux/usr/lib/arm-ostl-linux-gnueabi/gcc/arm-ostl-linux-gnueabi/13.3.0/include/limits.h:205:15: fatal error: limits.h: No such file or directory
205 | #include_next <limits.h> /* recurse down to the real one */ compilation terminated.

So do you actually have a limits.h file in your filesystem?

If you do, is it in a place where your compiler is looking? ie, somewhere covered by your Include Paths ?

PS:

Gstreamer has a forum here: https://discourse.gstreamer.org/ 

[SullyNiu]

I think these should be included in the cross-compilation toolchain, since the system is using gst-launch-1.0.

I finally figured it out

$CC basic-tutorial-1.c -o basic-tutorial-1 -I/opt/st/stm32mp1/5.0.3-openstlinux-6.6-yocto-scarthgap-mpu-v24.11.06/sysroots/cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi/usr/include/gstreamer-1.0 -I/opt/st/stm32mp1/5.0.3-openstlinux-6.6-yocto-scarthgap-mpu-v24.11.06/sysroots/cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi/usr/include/glib-2.0 -I/opt/st/stm32mp1/5.0.3-openstlinux-6.6-yocto-scarthgap-mpu-v24.11.06/sysroots/cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi/usr/lib/glib-2.0/include -lgstreamer-1.0 -lglib-2.0

Good news!

If that's resolved your issue, please Mark The Solution.

The compilation error indicates that the limits.h header file is missing during cross-compilation for the GStreamer HelloWorld example.

Not necessarily missing: As I said earlier, it could be present but not in a place where the compiler is looking.

In fact, I think this is the more common case?
