[Libreoffice] Error compilation on sc

Hello,

Since today when i compile, i've got this in sc module :
Entering /home/serval/libreoffice-source/libo/sc/source/ui/unoobj

`../../../unxlngi6.pro/slo/chart2uno.obj' is up to date
Entering /home/serval/libreoffice-source/libo/sc/util

Making:    scalc3c.lib
Making:    libscli.so
: ERROR: 
/home/serval/libreoffice-source/libo/solver/330/unxlngi6.pro/lib/libtkli.so: 
undefined symbol: 
_ZN3vcl15ImageRepository9loadImageERKN3rtl8OUStringER8BitmapExb
dmake:  Error code 1, while making '../unxlngi6.pro/lib/libscli.so'

Am i good for a make clean && make or is it something else ?

(If it could be useful, I can send a file with the result of build with 
verbose=1)

Julien.
