Description :
The include mechanism of plugin makefiles impact the oflags of the kernel compilation.
For example, the compilation flags of cmx for plugin is enriched with a -for-pack pluginname.
When one compiles frama-c classicaly, with VERBOSEMALE=yes make, one obtains:
ocamlopt ..... -for-pack Aorai structural_descr.ml and same for a lot of .ml files of the kernel such as external/unmarshal.ml, src/type/type.ml ...
A (not so nice) workaround is to compile first those cmx without call to any dynamic plugin and then the main call:
kernel only
EXTERNAL_PLUGINS="" VERBOSEMAKE=yes FRAMAC_USER_FLAGS="-for-pack FramaC" GEN_BUCKX_CFLAGS="-fPIC" make
remaining uncompiled plugins
VERBOSEMAKE=yes FRAMAC_USER_FLAGS="-for-pack FramaC" GEN_BUCKX_CFLAGS="-fPIC" make
install
sudo make install
Interestingly, removing such cmx compiled incorrectly with -for-pack Aorai, and asking to compile it again, triggers the correct rule:
#frama-c-Sodium-20150201$ rm src/type/structural_descr.cmx
#frama-c-Sodium-20150201$ VERBOSEMAKE=yes make src/type/structural_descr.cmx
It returns:
ocamlopt.opt -c -w +a-3-4-6-9-41-44-45-48 -annot -bin-annot -g -I src/misc -I src/ai -I src/memory_state -I src/toplevel -I src/slicing_types -I src/pdg_types -I src/kernel -I src/logic -I src/lib -I src/printer -I src/project -I src/type -I src/buckx -I src/gui -I external -I cil/src -I cil/src/ext -I cil/src/frontc -I cil/src/logic -I cil/ocamlutil -I /home/ploc/Local/src/frama-c/frama-c-Sodium-20150201/lib/plugins -I lib -I /home/ploc/.opam/4.01.0/lib/ocamlgraph -I /home/ploc/.opam/4.01.0/lib/zarith -compact src/type/structural_descr.ml
Strange, n'est ce pas?
