Compile Error in current master

[incaseoftrouble]

Hi,

I'm building checktestdata on WSL. When compiling on master, I get:

g++ -g -O2 -Wall -fstack-protector -fPIE -D_FORTIFY_SOURCE=2 -std=c++14 -DVERSION="\"20200702\"" -I/usr/include  -c -o parse.o parse.cc

The release branch builds successfully. I'm a C++ noob and I've no idea what you might need to help :-) Feel free to ask! Some versions:

• g++ (Ubuntu 7.5.0-3ubuntu1~18.04) 7.5.0
• bisonc++ V6.01.00
• flexc++ V2.06.02

Could you check if it works when you use the release branch? That one has pre-generated Bison/Flex parser code.

[incaseoftrouble]

$ git clone https://github.com/DOMjudge/checktestdata.git
$ cd checktestdata/
$ git checkout release
$ ./bootstrap
...
checking for boostlib >= 1.33.1... yes
configure: parser generation disabled
configure: creating ./config.status
config.status: creating config.mk
$ make

This works.

Maybe useful:

$ uname -a

Ok, that's good to hear.

I'll have to look into this a bit deeper. It's probably a combination of the Bisonc++/Flexc++ versions and the compiler version.
