[Barrelfish-users] Still Getting Errors While Compiling

[Baumann Andrew]

Hi all,

FWIW, I removed all the -section-start flags for x86_64, and it seems to work fine. We can probably do the same for x86_32 as well?

Hi Hamid

The text section has grown so that depending on compilation
environment it may overflow into the data section with the current
compilation flags. A quickfix is to move the beginning of the text
section to a lower address:

--- a/hake/X86_32.hs
+++ b/hake/X86_32.hs
@@ -45,7 +45,7 @@ cxxFlags = ArchDefaults.commonCxxFlags

 cDefines = ArchDefaults.cDefines options

-ourLdFlags = [ Str "-Wl,-section-start,.text=0x400000",
+ourLdFlags = [ Str "-Wl,-section-start,.text=0x300000",
               Str "-Wl,-section-start,.data.rel.ro=0x600000",
               Str "-Wl,-z,max-page-size=0x1000",
               Str "-Wl,--build-id=none",
