Hello I am having trouble identifying how to fix the following error we encounter when compiling AROS using our patched gcc 8.2. Compile failed: ccache /home/nick/builds/pc-x86_64-smp-gcc8/bin/linux-x86_64/tools/crosstools/x86_64-aros-gcc -iquote /home/nick/builds/pc-x86_64-smp-gcc8/bin/pc-x86_64-smp/Ports/acpica/acpica-unix-20190108/source/components/utilities/ -iquote /mnt/c/Users/kalam/AROS/svn-repo/AROS/arch/all-pc/acpica -iquote . -mcmodel=large -mno-red-zone -mno-ms-bitfields -O2 -fno-asynchronous-unwind-tables -fno-omit-frame-pointer -Wall -Werror -Wno-pointer-sign -Wno-parentheses -Wno-strict-aliasing -I/home/nick/builds/pc-x86_64-smp-gcc8/bin/pc-x86_64-smp/AROS/Developer/include/acpica -iquote /home/nick/builds/pc-x86_64-smp-gcc8/bin/pc-x86_64-smp/Ports/acpica/acpica-unix-20190108/source/include -iquote /home/nick/builds/pc-x86_64-smp-gcc8/bin/pc-x86_64-smp/Ports/acpica/acpica-unix-20190108/source/include/platform -DAROS_BUILD_TYPE=AROS_BUILD_TYPE_PERSONAL -I/home/nick/builds/pc-x86_64-smp-gcc8/bin/pc-x86_64-smp/gen/arch/all-pc/acpica/acpica/include -include /home/nick/builds/pc-x86_64-smp-gcc8/bin/pc-x86_64-smp/gen/arch/all-pc/acpica/acpica/include/acpica_deflibdefs.h -D__SRCFILENAME__="bin/pc-x86_64-smp/Ports/acpica/acpica-unix-20190108/source/components/utilities/utprint.c" -c /home/nick/builds/pc-x86_64-smp-gcc8/bin/pc-x86_64-smp/Ports/acpica/acpica-unix-20190108/source/components/utilities/utprint.c -o /home/nick/builds/pc-x86_64-smp-gcc8/bin/pc-x86_64-smp/gen/arch/all-pc/acpica/acpica/utprint.o /home/nick/builds/pc-x86_64-smp-gcc8/bin/pc-x86_64-smp/Ports/acpica/acpica-unix-20190108/source/components/utilities/utprint.c: In function 'sprintf': /home/nick/builds/pc-x86_64-smp-gcc8/bin/pc-x86_64-smp/Ports/acpica/acpica-unix-20190108/source/components/utilities/utprint.c:880:14: error: specified bound 4294967295 exceeds 'INT_MAX' [-Werror=format-truncation=] Length = vsnprintf (String, ACPI_UINT32_MAX, Format, Args); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors mmakefile:918: recipe for target '/home/nick/builds/pc-x86_64-smp-gcc8/bin/pc-x86_64-smp/gen/arch/all-pc/acpica/acpica/utprint.o' failed My problem is I cannot see where it is getting "INT_MAX" from as the bounds for the 2nd parameter. The documentation for vsnprintf says "If the *maxlen* value is 0, no characters are written, and *vsnprintf* returns 0. If the value is greater than *INT_MAX* , then *vsnprintf* behaves identically to *vsprintf* in that no limit checking is done on the number of characters written to the output area. No warnings concerning length errors are produced by *vsnprintf* , and the only indication that the output may have been truncated or is incomplete is a negative return value." We expose vsnprintf in our stdio.h as -: int vsnprintf(char * restrict s, size_t n, const char * restrict format, va_list arg); where size_t is typedef'd as -: typedef long unsigned int size_t; and SIZE_MAX is defined -: # if __WORDSIZE == 64 # define SIZE_MAX UINT64_MAX # else # define SIZE_MAX UINT32_MAX # endif Any suggestions on how to approach this would be greatly appreciated.
