Bug: `postgis_compile.sh` fails to build protobuf-c-1.4.0 due to missing `autogen.sh`

postgis_compile.sh: Incorrect autogen.sh call for protobuf-c-1.4.0 tarball builds

Problem Description:

When I following the "How to install" guide for postgis-for-opentenbase, the postgis_compile.sh script fails during the compilation of protobuf-c-1.4.0. The script attempts to execute autogen.sh, but this file is not present in the protobuf-c-1.4.0 source tarball. This leads to a build failure.

Environment:

• OpenTenBase: master branchb612d77
• OS: Rocky Linux 8.10 (Green Obsidian) running on VMware® Workstation 17 Pro
• postgis-for-opentenbase main branch5f6901a

Steps to Reproduce:

1. Follow the "How to install" instructions in the postgis-for-opentenbase README.md up to the "Compile dependency & postgis" section.
2. Execute ./postgis_compile.sh.
3. Observe the build output, specifically during the protobuf-c-1.4.0 compilation phase.

Expected Behavior:

The protobuf-c-1.4.0 library should compile successfully, as its source tarball (v1.4.0) already contains a generated configure script, making the autogen.sh step unnecessary.

Actual Behavior / Error Log Snippet:

The build fails with an error similar to:

···
start compile protobuf-c-1.4.0......
/data/opentenbase/OpenTenBase/contrib/protobuf-c-1.4.0
chmod: cannot access 'autogen.sh': No such file or directory

Additional Information:

[opentenbase@sc contrib]$ ls ./protobuf-c-1.4.0
aclocal.m4   ChangeLog    configure.ac       LICENSE      Makefile.in  README.md
build-aux    config.h.in  Doxyfile.in        m4           protobuf-c   t
build-cmake  configure    DoxygenLayout.xml  Makefile.am  protoc-c     TODO

As shown, configure exists, but autogen.sh does not.

Suggested Fix :

The postgis_compile.sh script should be modified to skip the autogen.sh step for protobuf-c-1.4.0 and instead directly use the existing configure script.

Specifically, change these lines:

chmod +x autogen.sh
./autogen.sh
./configure --prefix=${prefix_args} CPPFLAGS=-I${prefix_args}/include LDFLAGS=-L${prefix_args}/lib

To:

# chmod +x autogen.sh
# ./autogen.sh
chmod +x configure
./configure --prefix=${prefix_args} CPPFLAGS=-I${prefix_args}/include LDFLAGS=-L${prefix_args}/lib

This adjustment allowed me to successfully compile and install PostGIS for OpenTenBase.
