makefile - How to install a lua module in a subdirectory of libdir with the autotools -


i have written little lua module complile using autotools , want modify organization:

now have in main directory:

autogen.sh configure.ac makefile.am src     file1.c     file2.c     file3.c

the autogen.sh

 #!/bin/sh  echo "running aclocal..." ; aclocal $aclocal_flags || exit 1  echo "running libtoolize..."; libtoolize --copy --automake || exit 1;  echo "running autoheader..." ; autoheader || exit 1  echo "running autoconf..." ; autoconf || exit 1  echo "running automake..." ; automake --add-missing --copy --gnu || exit 1  ./configure "$@"

the configure.ac

#                                               -*- autoconf -*- # process file autoconf produce configure script. ac_prereq([2.69]) ac_init([lua-clangc], [0.0.1], [cedlemo@gmx.com]) ac_config_srcdir([configure.ac]) ac_config_headers([config.h]) # checks programs. ac_prog_cc(clang gcc) # checks libraries. pkg_check_modules([deps], [lua]) #lua_version = $(pkg-config --version) #ac_subst([lua_version]) # checks header files. ac_check_headers([string.h stdlib.h clang-c/index.h]) # checks typedefs, structures, , compiler characteristics. # checks library functions. am_init_automake(1.13 dist-bzip2 foreign subdir-objects) lt_prereq(2.4) lt_init ac_config_files([   makefile ]) ac_output

and makefile.am

maintainercleanfiles = \ makefile.in aclocal.m4 config.h.in configure \ depcomp install-sh missing compile config.sub \ config.guess ltmain.sh compile  lib_ltlibraries = src/clangc.la src_clangc_la_sources = src/clangc.c src/indexlib.c src/translationunitlib.c src/constants.c src/clangc_module_functions.c src_clangc_la_ldflags = -module -avoid-version -shared -llua -lm -lclang -fpic

i use commands compile , install lua module:

./autogen.sh --libdir=/usr/lib/lua/5.3 make sudo make install

my files installed in /usr/lib/lua/5.3

/usr/lib/lua/5.3/clangc.so /usr/lib/lua/5.3/clangc.la

i use 

./autogen.sh --prefix=/usr

and configure.ac script build libdir this:

libdir=prefix + /lib/lua/ + lua_version + /clangc/

(i have way lua_version in configure.ac)

as answer myself:

i have modify configure.ac this:

ac_prereq([2.69]) ac_init([lua-clangc], [0.0.1], [cedlemo@gmx.com]) ac_config_srcdir([configure.ac]) ac_config_headers([config.h])  # checks programs. ac_prog_cc(clang gcc)  # checks libraries. pkg_check_modules([deps], [lua]) lua_version=$(pkg-config --modversion lua | awk -f "." '{print $1"."$2}') ac_subst([lua_version])  libdir=$prefix/lib/lua/$lua_version/clangc # checks header files. ac_check_headers([string.h stdlib.h clang-c/index.h])  # checks typedefs, structures, , compiler characteristics.  # checks library functions. am_init_automake(1.13 dist-bzip2 foreign subdir-objects) lt_prereq(2.4) lt_init ac_config_files([   makefile ]) ac_output

first had find current lua version:

lua_version=$(pkg-config --modversion lua | awk -f "." '{print $1"."$2}')

on system:

  • pkg-config --modversion lua returns 5.3.1
  • awk -f "." '{print $1"."$2}' returns 5.3

then line: 

libdir=$prefix/lib/lua/$lua_version/clangc

do magic.

when use:

./autogen.sh --prefix=/usr

my lib installed in:

/usr/lib/lua/5.3/clangc

i rendering jbutton image on simulate jcheckbox behavior. why don't let jtable render jcheckbox? because need bigger checkboxes , there's no way can resize them (as far know). so, have own table cell renderer , editor. both renders jbutton , checkbox images on them. trying change image checked image unchecked image (or vice versa) , update cell value (boolean true or false). however, reason, getcelleditorvalue() not update table. so, release mouse, value goes original one. any appreciated! lot! public class tableexample extends jframe { jscrollpane pane; jpanel panel; jtable table; object[][] data; mytablemodel tm; renderer buttoncolumn; public tableexample(object[][] data) throws ioexception { string[] columns = {"column#1", "column#2", "column#3", "column#4", "column#5", "column#6"}; this.data = data; this.setpreferredsize(new dimension(700, 500));
