halcompile missing additionnal include file

Hi,

i'm working on userspace wj200_vfd
i've added a local include file wj200_vfd.h in the declaration section of the comp file
and halcompile --preprocess works fine and generate .c file to the local folder
when invoking
halcompile --compile wj200_vfd.comp
i get
fatal error: wj200_vfd.h: No such file or directory
it seems .h file is not copied to the temp directory where the wj200_vfd.c file is generated

as a workaround i added it manually to the gcc cmd line generated using halcompile --compile wj200_vfd.comp

but is there a way to properly add missing .h file either by having the missing file copied to the temp directory or to force
halcompile --compile not to use a temp dir or something else ?

thanks
OR

thanks for the update

for the record, there is also a an hidden option "extra_compile_args"
not in the doc here linuxcnc.org/docs/html/hal/comp.html#_options
but looking at the source here
github.com/LinuxCNC/linuxcnc/blob/master...l/utils/halcompile.g
line 715

i just tried to add this in the declaration of the .comp file
option extra_compile_args "-I/home/linuxcnc/dev/linuxcnc-oro06.git/src/hal/user_comps/wj200_vfd/";
and that did the trick but it's not a relative path, not sure it's nice for a
future pull request to come !

still this was usefull with modbus.h which is not in the path

option extra_compile_args "-I/home/linuxcnc/dev/linuxcnc-oro06.git/src/hal/user_comps/wj200_vfd;-I/usr/include/modbus";

typo
option extra_compile_args "-I/home/linuxcnc/dev/linuxcnc-oro06.git/src/hal/user_comps/wj200_vfd -I/usr/include/modbus -std=c99";

Hi,

It can be Orinaudo has used the include statement not the right way.

In Andy's example, in my case nothing will be found with : include "../../../hal/drivers/mesa-hostmot2/hostmot2.h";
Even if the file exist's.
So i suspect mr. Orinaudo can have typed a wrong include argument for a component .comp file to halcompile.

For example, this works, it find's it :
#include "/opt/etherlab/include/special.h"
( if the file exist's )

hi,
sorry to my unclear question,
but the interest was also in not polluting .comp sources
with pathfilename dependant on where code source tree is located
as a concrete example, of out-of-tree compiling component, with the current master
, speaking of the wj200_vfd.comp located (in my case)
~/linuxcnc/dev/linuxcnc/src/hal/user_comps/wj200_vfd
then to fix this, a possibility is to add in the comp file, in the declaration section (before the ";;")this should succeed, i find it clean because modbus is a std lib located in a std place

now if one want to use an additionnal include file wj200_vfd.h, located in the same directory as the comp
updating the corresponding .comp file like this
then compiling...replacingbywill compile fine on my system,
but this will not compile properly on another system located elsewhere in the fs

this is why i proposed
