Compile cximage in Linux

There is a cximage source package that is said to be able to be compiled in Linux on the Internet, but there are several problems encountered during compilation:

1. All eight subdirectories must be compiled.
Cximage j2k Jasper jbig jpeg png tiff zlib
Generate eight static databases. Indispensable.
The original makefile only generates five lib
Convert subdirs = zlib JPEG tiff PNG cximage of the original makefile
To:
Subdirs = zlib JPEG tiff PNG cximage j2k Jasper JBIG
Alternatively, you can manually enter a separate make file under the subdirectory. Equivalent Effect.

2. An error occurred while compiling the file jpc_cs.c when libjasper. A was generated, prompting undefined ulong.
Very strange. Manually add the Definition Statement to the file jpc_cs.h:
# Ifndef ulong
Typedef unsigned long ulong;
# Endif

3. Wrote a simple test.ProgramDemo: add all eight lib libraries. The command is as follows:
Gcc-O demo. O-l ../build-Linux-l cximage-l j2k-l JPEG-l JBIG-l Tiff-l PNG-l zlib-l Jasper
A large number of errors are prompted (the error messages are all garbled, unreadable, and dizzy .. I guess I cannot find anything used in Lib), and so on:
.. /Build-Linux/libcximage. A (ximapcx. o): ximapcx. CPP :(. text + 0xa25) when there are too many errors _ cxa_allocate_exception when there are too many errors
I used a bunch of garbled code to go to Google and found something. Find the one that says you want to add-lstdc ++
I tried it. It is feasible.
(Google stuff: Glibc and stdc ++ are not included in GCC. If C or C ++ is used,
When linking, we need to add the corresponding library glibc or stdc ++. If not, compile it by yourself .)

4. Make the example complex and add read conversion. Connection error:

../Build-Linux/libjasper. A (jpg_enc.o)
../Build-Linux/libjasper. A (jpg_dec.o)
The specific error is not clear, garbled, and only the connection error is known. Very strange.
Copy the O files of the two files to the demo directory and manually add them when generating the files:
Gcc-O demo. O jpg_enc.o jpg_dec.o-l .. /build-Linux-l cximage-l j2k-l JPEG-l JBIG-l Tiff-l PNG-l zlib-l Jasper-lstdc ++
Compiled. The operation is correct.

Too many are unclear. Linux is too difficult. Adapt slowly ~~~
