I think I only needed to nstall these 3, but the 2nd one gives me some <br>
trouble:<br>
<br>
libgpiod-1.4.1-2.el7.armv7hl.rpm<br>
libgpiod-devel-1.4.1-2.el7.armv7hl.rpm<br>
libgpiod-utils-1.4.1-2.el7.armv7hl.rpm<br>
<br>
[root@localhost libgpiod.rpms]# rpm -ivh <br>
libgpiod-devel-1.4.1-2.el7.armv7hl.rpm<br>
error: Failed dependencies:<br>
libgpiodcxx.so.1 is needed by libgpiod-devel-1.4.1-2.el7.armv7hl<br>
<br>
<br>
is the 2nd one, libgpiod-devel-1.4.1-2.el7.armv7hl.rpm, the one that has <br>
the header files in it?<br>
<br>
When I compile something simple I found:<br>
<br>
$ make<br>
cc main.c -lgpiod -D CONSUMER=\"libgpiod-led\" -o libgpiod-led<br>
main.c:1:19: fatal error: gpiod.h: No such file or directory<br>
#include <gpiod.h><br>
^<br>
<br>
I did a 'find' on the whole filesystem, I don't seem to have it anywhere.<br>
<br>
<br>
thanks,<br>
<br>
<br>
Ron<br>
