Problem with custom build step [message #930278]

Tue, 02 October 2012 06:56

Eclipse User

Hello,

In a project I tried to add a custom build step for a source file:

Additional input file name(s):
<Empty>

Output file name(s):
../src/df3441/%.o

Command:
ccv850 -dTPI -dDATALOG -dNECV850 -w -noundefined -elf -b0 -cg_underscore
-c "$<" -o "$@" -I$(dir $<) -I$(dir $<)/v850_include

Using these settings I can build the application once. But the second
(and succeding) time(s) I try to build I get the following error:

!ENTRY org.eclipse.core.resources 4 75 2012-10-02 08:45:19.256
!MESSAGE Errors occurred during the build.

I found similar behavior.

See if this helps:

In summery, once I enabled a build step on a resource file, builds had errors, and even closing and opening the project had errors. After this, to fix my project I had to edit .cproject file, changing every occurrence of 'override' to 'disable', and then reopen the project in eclipse.

The work-around, until I heard a better idea, is to set the build step at the project level, which isn't great, because I would prefer the build step only run when the resource file changes.
