<p style="background-color: rgb(255, 255, 255);" class="">I am trying to build a cross compiling tool-chain for Barrelfish. I am following the instructions on the wiki page, from a clean Ubuntu 16.04 LTS VM (it only contains barrelfish and its dependencies).</p>
<p style="background-color: rgb(255, 255, 255);" class="">I am using the recommended versions of binutils (2.24) and gcc (4.9.2) and the associated patches. However, I get a bunch of errors along the lines of:</p>
<p style="background-color: rgb(255, 255, 255);" class=""><tt class="">libstdc++-v3/include/cr16-elf/bits/ctype_base.h:48: error: '_U' was not declared in this scope</tt></p>
<p style="background-color: rgb(255, 255, 255);" class="">This seems to be due to gcc using the default system headers when compiling libstdc++-v3 which is fair enough since we have not told it not too. The source tree does seem to specify an obvious sysroot
(the source tree's usr/ directory does not contain include files), I assumed the system headers to be in the include/ directory of the source tree. As far as I have understood (I am probably wrong) they are meant to be a port of newlib to barrelfish. However
even after configuring the build with <code class="">--with-native-system-header-dir=<var class="">"${BARRELFISH_SOURCE}/include"</var></code> the error persists. After examining these files they do not implement a newlib style ctype.h and thus do not define
the above macros.</p>
<p style="background-color: rgb(255, 255, 255);" class="">Is this a known-issue and is there a known workaround? Are the headers in include/ not a port of newlib in which case the configure option <tt class="">--with-new-lib </tt>is not correct? In short what
am I doing wrong?<br class="">
</p>
<p style="background-color: rgb(255, 255, 255);" class="">Again, sorry to bother everyone with trivial matters.</p>
