Compiling on Ubuntu

[chaoticmachinery]

When I try configuring this under Ubuntu I get the following:

checking linux/gpio.h usability... no checking linux/gpio.h presence... no checking for linux/gpio.h... no configure: error: linux/gpio.h header not found (needed to build the library)

I have confirmed that the linux headers are installed. /usr/src/linux-headers-4.10.0-40/include/linux/gpio.h

Is there something else I need to give configure?

Thank you, CM

This file should be in /usr/include/linux/gpio,h. On my debian 9 system it's provided by linux-libc-dev. Alternatively you can pass CFLAGS="-I/usr/src/linux-headers-4.10.0-40/include" to the configure script to let it know the location of the header.

Still doesn't work:

try this

git clone https://git.kernel.org/pub/scm/libs/libgpiod/libgpiod.git cd libgpiod mkdir -p include/linux cp /usr/src/linux-headers-$(uname -r)/include/linux/compiler_types.h include/linux/. ./autogen.sh --enable-tools=yes --prefix=/usr/local CFLAGS="-I/usr/src/linux-headers-$(uname -r)/include/uapi -Iinclude" make sudo make install sudo ldconfig

let me know if works for you as work for me on Mint 18.3

[romainreignier]

@InvalidExcepti0n It works for me with warnings because I was using kernel headers. Thanks.

I was Ubuntu 16.04 with kernel 4.10 and the compiler_types.h file was not there so I have copied compiler* files.

[gustavojcorrea]

@romainreignier I also don't have the compiler_types.h file. Could you please provide a bit more information on your process to solve this issue? Thank you

[romainreignier]

@gustavojcorrea I have followed @InvalidExcepti0n instructions except that I replaced this line:

cp /usr/src/linux-headers-$(uname -r)/include/linux/compiler_types.h include/linux/.

by this one

cp /usr/src/linux-headers-$(uname -r)/include/linux/compiler* include/linux/.

[gustavojcorrea]

@romainreignier When I use cp /usr/src/linux-headers-$(uname -r)/include/linux/compiler* include/linux/. I get the following cp: cannot stat '/usr/src/linux-headers-4.9.54-ti-r68/include/linux/compiler*': No such file or directory

@chaoticmachinery can I close this? I can't really help you, I don't use ubuntu. I think this question belongs on a ubuntu support forum.
