[cdt-dev] MBS in CDT 2.1 - defining toolchain with post linking steps not supported?
|
Hi
all,
I am running into
troubles with extending the current (CDT 2.1) Managed Build System for my
embedded platform. Here is the problem:
I created a
Configuration that will ultimately produce a binary Image for the Gameboy
advance. To do so, I need to accomplish the following steps:
1) compile .c ->
.o
2) link .o
-> .elf
3) run a objcopy on
the elf to produce the ROM file
Therefore, I
extended the MBS (org.eclipse.cdt.managedbuilder.core.buildDefinitions), and
added a toolchain as follows:
Tool1 (Compiler):
input: .c output: .o
Tool2 (Linker): input: .o output: .elf
Tool3
(Objcopy): input: .elf output: .gba
I have set my artifact extension (which i think is
the final extension
required to build the result of the managed make
process), to "gba"
,and this is what happens when i attempt to
compile:
make -k all
Building file:
../sdf.c
arm-elf-gcc -c -osdf.o ../sdf.c
Finished building:
../sdf.c
Building target: sdfsdf.gba
<------------------------ PROBLEM: it did not run Tool2
(Linker)
arm-elf-objcopy sdfsdf.gba sdf.o
c:\dka\bin\arm-elf-objcopy.exe: 'sdfsdf.gba': No such file
make: ***
[sdfsdf.gba] Error 1
make: Target `all' not remade because of
errors.
After a good
discussion of this issue on the newsgroup, I am wondering if the problem with
the current implementation of the CDT MBS may be as follows:
At the time of
makefile generation, the only resources that are
available in the
project will be ".c" files, and the information that
".gba" is to be
built.
So I wonder if this
may be whats happening in the MakefileGenerator
1) finds .c files
and adds rules to transform them to .o
2) finds no other resources (as
nothing was built yet), but knows it
needs to generate ".gba"
3) and
therefore adds Tool3 (which it knows produces .gba), feeding it with ".o"
instead of ".elf"
Any help on how to
get such a toolchain working would be much appreciated
all the
best
Emanuel
PS: this issue has
been discussed by a few people on the newsgroup, but ultimately, we did not yet
manage to come up wuth a solution - so i am posting this to the email
list.
