autoreconf error, 2.69 #53

Open JohnWulff opened 7 months ago

JohnWulff commented 7 months ago

I have cloned libgpiod from this web site (brgl/libgpiod). I am having problems building libgpiod. I am running the software on a Raspberry PI 3B+ using Raspbian Buster OS. I have successfully used sysfs in the run-time of my event-driven language immediate C for over 8 years to set GPIO outputs and generate interrupts from GPIO inputs and read them. Since sysfs is deprecated I want to migrate my code to libgpiod.

I installed the following: apt install autoconf apt install autoconf-archive

I initially executed: sudo apt install gpiod libgpiod-dev libgpiod-doc Trying to compile examples from that install showed that the gpiod.. C functions were not present. I then cloned libgpiod. Following the Build instructions I executed: ./autogen.sh --enable-tools=yes --prefix=/usr/local This output the following error messages: autoreconf: Entering directory.' autoreconf: configure.ac: not using Gettext autoreconf: running: aclocal --force -I m4 aclocal: warning: couldn't open directory 'm4': No such file or directory autoreconf: configure.ac: tracing autoreconf: configure.ac: not using Libtool autoreconf: running: /usr/bin/autoconf --force autoreconf: running: /usr/bin/autoheader --force autoreconf: running: automake --add-missing --copy --force-missing bindings/cxx/Makefile.am:4: error: Libtool library used but 'LIBTOOL' is undefined bindings/cxx/Makefile.am:4: The usual way to define 'LIBTOOL' is to add 'LT_INIT' bindings/cxx/Makefile.am:4: to 'configure.ac' and run 'aclocal' and 'autoconf' again. bindings/cxx/Makefile.am:4: If 'LT_INIT' is in 'configure.ac', make sure bindings/cxx/Makefile.am:4: its definition is in aclocal's search path. lib/Makefile.am:4: error: Libtool library used but 'LIBTOOL' is undefined lib/Makefile.am:4: The usual way to define 'LIBTOOL' is to add 'LT_INIT' lib/Makefile.am:4: to 'configure.ac' and run 'aclocal' and 'autoconf' again. lib/Makefile.am:4: If 'LT_INIT' is in 'configure.ac', make sure lib/Makefile.am:4: its definition is in aclocal's search path. tests/gpiosim/Makefile.am:4: error: Libtool library used but 'LIBTOOL' is undefined tests/gpiosim/Makefile.am:4: The usual way to define 'LIBTOOL' is to add 'LT_INIT' tests/gpiosim/Makefile.am:4: to 'configure.ac' and run 'aclocal' and 'autoconf' again. tests/gpiosim/Makefile.am:4: If 'LT_INIT' is in 'configure.ac', make sure tests/gpiosim/Makefile.am:4: its definition is in aclocal's search path. tools/Makefile.am:7: error: Libtool library used but 'LIBTOOL' is undefined tools/Makefile.am:7: The usual way to define 'LIBTOOL' is to add 'LT_INIT' tools/Makefile.am:7: to 'configure.ac' and run 'aclocal' and 'autoconf' again. tools/Makefile.am:7: If 'LT_INIT' is in 'configure.ac', make sure tools/Makefile.am:7: its definition is in aclocal's search path. autoreconf: automake failed with exit status: 1`

I do not know to what path or where exactly to set LT_INIT

autoreconf: configure.ac: not using Libtool

Could you check whether you have libtool installed?

JohnWulff commented 7 months ago

No libtool found. I have now done sudo apt install libtool This adds the directory /usr/share/libtool

./autogen.sh --enable-tools=yes --prefix=/usr/local seems to be working except for the following warning: autoreconf: running: aclocal --force -I m4 aclocal: warning: couldn't open directory 'm4': No such file or directory

make OK Vielen Dank, John

JohnWulff commented 7 months ago

make install fails because it requires super-user privileges. sudo make install OK

You may want to modify the Build instructions in the README.
