Can you paste the output of the following command:
readelf -h $(SGX_SDK_DIR)/build/linux/sgx_sign

also I find a question,When my system's language is English,it will build 64bit installer,but other language is x86

The installer build script simply reads the magic number of sgx_sign to determine it is x86 or x64. The parser may get the wrong number from a different language other than English. You can find the parser from get_arch() in linux/installer/bin/build-installpkg.sh.

Can you give the result of file -L /bin/sh for another language except English?

@llly In Chinese ,the readout of file -L /bin/shis

@yuyuany I find build-installpkg.sh and I will try to change some code to build x64 installer

The colon ： is fullwidth in CJK computing. So awk '/:/{print $6}' does not work. The simplest solution is to remove /:/ on https://github.com/intel/linux-sgx/blob/master/linux/installer/bin/build-installpkg.sh#L60
