Hello,
I have a project that isn't part of Fedora yet - though really I
should add it at this point. Its php-cpp. It allows me to write c++

F32 beta and now when compiling anything that includes its headers
compilation fails and I'm not entirely sure why.
g++ -MT pdf-image.o -MMD -MP -MF .d/pdf-image.Td -Wall -g -c -O2
-std=c++11 -fPIC `pkg-config poppler-cpp fontconfig openssl --

In file included from /usr/include/phpcpp.h:38,
from pdf-image.cpp:8:
/usr/include/phpcpp/throwable.h:29:1: error: expected class-name before
‘{’ token
It's telling you the token before the opening brace is not a
class-name. Look at the token. See why GCC thinks it's not a
class-name. The most likely reason is it's not been declared (which is
exactly what Jakub confirmed, the laborious way of actually checking
the preprocessed source).
I've attached the header. Any gcc experts out there able to tell me
what's wrong with the header format that used to compile but no longer
does?
It's not a GCC question, it's a C++ one. You didn't include the
header for something you're using.

Please mail me a preprocessed source instead (e.g. rerun the g++ command
line with -save-temps option and mail pdf-image.ii the compiler creates,
or drop -M* options and their arguments, change -c to -E and pdf-image.o
to pdf-image.ii).
So, from the offlist posted preprocessed source, seems the TU includes the
following libstdc++ headers
#include
#include
#include
#include
#include
#include
#include
and then uses std::runtime_exception. That one is defined in
header though, and is not included. Before
https://gcc.gnu.org/legacy-ml/libstdc++/2019-06/msg00032.html
change it has been included as implementation detail from headers included
in , or from the above list.
So, you just need to make sure is also included if you need
classes from it.
Which is documented in the (incomplete) release info for gcc-10:
https://gcc.gnu.org/gcc-10/porting_to.html#header-dep-changes
