Can you please attach your compile log and your configure.wps file? Thanks!

Thanks for your quick reply! I am new user for linux os, so I forgot to attach them. Thank you for your reminder, I will attach them below.

Fellowing kwerner's suggestion,I checked my compile.log and I found the fatal error below:

gcc -c -D_UNDERSCORE -DBYTESWAP -DLINUX -DIO_NETCDF -DBIT32 -DNO_SIGNAL -I/home/qingyunlee/APP/APP_General/jasper_version_1.900.1/include -DUSE_JPEG2000 -DUSE_PNG -D__64BIT__ dec_png.c
dec_png.c:5:10: fatal error: png.h: No such file or directory
5 | #include <png.h>
| ^~~~~~~
compilation terminated.
But I had add libpng/lib in CPPFLAGS as
echo $CPPFLAGS
-I/home/qingyunlee/APP/APP_General/jasper_version_1.900.1/include -I/home/qingyunlee/APP/APP_General/libpng_version_1.6.40/include
should I must configure jasper and libpng in the same directory? I don't know how to fix it

Hi,
Yes, jasper, libpng, and zlib should all be compiled in the same directory, so that inside that directory, there will be an "include" and "lib" directory, which will contain the files for all three of these libraries. Take a look at this compiling tutorial to see how we suggest to build those libraries.

It is work! thanks that you let me know!
