I'll probably take your at and perf patches, my gcc one which covers
the cross and candadian variants and merge a change to the sstate
dependency code which means we'll explicitly see these dependency
issues in future. I'll queue this in -next and test.

Cheers,

Richard

Thanks. I was building native gcc for the target, while using external 
prebuilt cross toolchain. I first tried adding flex-native to NATIVEDEPS 
list, but that didn't help - looks like this list is only used for cross and 
crosssdk builds.

Agreed, however I think we have bigger problems. I'm testing with this:

probably in addition to your patch. I'll continue to run some test

[OE-core] [PATCH] gcc: add flex-native explicit dependency

[Denys Dmytriyenko]

From: Denys Dmytriyenko 

It seems flex is required to build gcc:

| .../work-shared/gcc-7.2.0-r0/gcc-7.2.0/missing: line 81: flex: command not 
found
| WARNING: 'flex' is missing on your system.
|  You should only need it if you modified a '.l' file.
|  You may want to install the Fast Lexical Analyzer package:
|  
| Makefile:2799: recipe for target 'gengtype-lex.c' failed
| make[1]: [gengtype-lex.c] Error 127 (ignored)

Normally this is handled indirectly throught binutils-cross dependency
pulling in flex-native implicitly. For deterministic builds, this should
be specified explicitly.
