When compiling a large project file with Makefile, the following error occurred, indicating that the parameter list is too long, and the gcc command suffix cannot exceed more than 8000 bytes.
By checking the data, the suffix list of gcc can be put into a file, and the Argument list too long can be solved by means of gcc @file.

@file
Read command-line options from file. The options read are inserted in place of the original @file option. If file does not exist, or cannot be read, then the option will be treated literally, and not removed.
Options in file are separated by whitespace. A whitespace character may be included in an option by surrounding the entire option in either single or double quotes. Any character (including a backslash) may be included by prefixing
the character to be included with a backslash. The file may itself contain additional @file options; any such options will be processed recursively.Modify Makfile, redirect the location of the header file to a specific file, and then compile with gcc @file:

$(ATECH_USER_LINKFLAGS) Although this can solve the problem, it only puts the path of .h into the file, and the path of .o file is not added to the file, and this way of writing is too verbose. If the following modifications are made, use the foreach function in the Makefile to cut the corresponding After the environment variable, redirect to the file:

$(ATECH_USER_LINKFLAGS) After compiling again, the following error occurs:
gcc region `BMHDO‘ overflowed by xxx bytes
The reason for this is that the size of the firmware exceeds a specific size, modify the link script, my link script vLinkGen_Template.ld here, here is printed out through a specific environment variable LDFLAGS.
-T script is to specify the ld link script
Modify the linker script to increase the size of the BMHDO section :
