Optimization #6126
opencompiling with outdated cbindgen does not have a corresponding err msg
Description
Observed when compiling with the current master.
When compiling suricata with an outdated cbindgen , there is no err message indication this is the actual problem by the resulting errors and the compilation fails.
A regular user following the docs would not be able to figure it out by themselves i think.
We should probably have a minimum cbindgen version that is needed to compile with (just as we do with rust).
Example of the errs that are related to older cbindgen :
./../rust/gen/rust-bindings.h:4794:3: error: typedef redefinition with different types ('struct AppLayerTxData' (aka 'AppLayerTxData') vs 'struct AppLayerTxData')
} AppLayerTxData;
^
./detect.h:1333:31: note: previous definition is here
typedef struct AppLayerTxData AppLayerTxData;
^
