Can i use cre2 if i don't want to install? about cre2 HOT 3 CLOSED

Yes, configure the package to build static libraries, build it, then configure your compiler to search for the header file in the subdirectory src of cre2's source directory and to search for cre2's static library in the subdirectory .libs of the build directory.

Thank you very much, when i install CRE2 in my linux system, it generates the directories in my computer ,like:

├── include
│   └── cre2.h
├── lib
│   ├── libcre2.a
│   ├── libcre2.la
│   ├── libcre2.so -> libcre2.so.0.0.0
│   ├── libcre2.so.0 -> libcre2.so.0.0.0
│   └── libcre2.so.0.0.0
└── share
    └── doc
        └── cre2
            ├── COPYING
            ├── LICENSE.re2
            └── README

I moved this directory to a computer which not install the CRE2, and add the add the include directory to the C_INCLUDE_PATHand use the static libraries libcre2.a to generate binary file like:

gcc main.cc -g -o main libcre2.a

But it always failed.Could you please show me some example how to configure the packageto build the static libraries, and how to use use it? Thank you very very much!!

Moving around compiled code like this is not a good idea if you are not at least a bit expert on using the compiler and linking libraries. Anyway, you can still try.

I will assume that the build system and the target system are both 32-bit or both 64-bit. I will assume that the target system has re2 installed. You should really read the documentation of gcc:

• You must use the command line option -L of gcc twice: to select the directory under which libcre2.a is installed and to select the directory under which libre2.a or libre2.so is installed.

• You must use the command line option -l of gcc twice: to request linking of libcre2.a and to request linking of libre2.a or libre2.so.

• You must use the command line option -I of gcc once: to select the directory under which cre2.h is installed.

You never write which error do you see when things go wrong. Surprisingly, this is a useful information!
