Пытаюсь собрать gnash с включенной опцией precompiled headers - возникает проблема: хедер создается, но при попытке использования gcc ругается на то, что он был создан с другими ключами
cc1plus: warning: ../all-includes.h.gch: created and used with different settings of -fpie [enabled by default]
cc1plus: error: one or more PCH files were found, but they were invalid
Я не вижу особых различий в ключах компилятора:
g++ -DHAVE_CONFIG_H \
-D_FORTIFY_SOURCE=2 -g -O2 -W -Wall -Wcast-qual
-Wpointer-arith -Wreturn-type -Wnon-virtual-dtor -Wunused
-fvisibility-inlines-hidden -fPIE -fstack-protector --param

-fPIC (единственное замеченное существенное отличие) пробовал убирать - не помогает.
В чем причина?
