Figure 1 Error message

Possible Causes

When multiple GCC versions are installed in the environment, the GCC of a later version in the default installation path is used for CCEC compilation. However, during the installation of the GCC of a later version, some files are missing. As a result, the cstdint header file cannot be found.

The locating process is as follows:

1. Run the following command to check the GCC status in the environment:

   1 2	cd /usr/lib/gcc/aarch64-linux-gnu ll

   The following command output shows that two installation directories (GCC 11 and GCC 12) exist.

   

2. Run the following command to query the GCC version in the environment:

   1	dpkg -l | grep gcc

   The following command output shows that two versions (GCC 11 and GCC 12) exist.

   

3. Check whether the header file exists in each version, and find that the header file exists only in the GCC 11 version. The path is as follows:

   1	/usr/include/c++/11/cstdint

Solution

Run the following command to uninstall GCC 12 and use the installed GCC 11 for compilation:

1

apt remove gcc-12 libgcc-12-dev
