*.tpp files throw syntax error

[Chasikanaft]

Hello there
What I got when I tried to load this library into vcpkg:

Severity Code Description Project File String Suppression Status
Error C2760 syntax error: expected token ';' not 'id' wtf c:\temp\vcpkg\installed\x64-windows\include\matiocpp\impl\multidimensionalarray.tpp 70

I tried compiling the dll and lib via just cmake on VS2017 and got the same results...

What am I doing wrong?)

[S-Dafarra]

Hi @Chasikanaft, thanks for opening the issue. Could you please post here the commands you run with cmake and the corresponding output?

[Chasikanaft]

Thank you for your quick reply, if I understood correctly:
this a cmake config:

This a tests results on VS2017 RUN_TESTS build.

Looking at the output of the tests, I see the error

Unable to find executable: C:/Softtools/matio-cpp-master/Build/bin/Release/ExogenousConversionsUnitTests.exe

This may mean that the compilation was not completed successfully. Could you please paste here the ALL_BUILD output? Did you have to edit the matioCpp CMakeLists in any way?

[Chasikanaft]

[traversaro]

The tests are failing because the compilation of the test is failing, so the original error are the compilation errors C2061, C2143, etc etc. In the CI we never test VS2017, only VS2019, so it is possible that that files does not support VS2017 at all. If you could use VS2019, I guess everything should work smooth. Anyhow, if the only objective is using other functionalities of the library that work fine under VS2017, probably you could just set BUILD_TESTING to OFF?

[Chasikanaft]

Build was successful but I can't use the library..
When adding the "include" directory to the project properties (Is it mandatory, right?) to the project (taking into account the addition of all lib and dll), it gives an error "*.tpp" file, which is the case with vcpkg, which is the usual addition of dll, lib, and include dir. (see first post)

[traversaro]

Ah ok, so you basically have the same error of the test but in your code? Then I guess the only option is to update to VS2019.

[S-Dafarra]

I think it could also be related to the version of visit_struct. Can you try unticking USE_SYSTEM_visit_struct in the CMake configuration?

[Chasikanaft]

Its no like test error, its different error like that:
Looks like simple syntax error, but why.

[Chasikanaft]

I think it could also be related to the version of visit_struct. Can you try unticking USE_SYSTEM_visit_struct in the CMake configuration?

all build succesfully without tests, but syntax error throw just into include

[S-Dafarra]

I would separate two problems at the moment:

1. Standalone compilation failures (*.tpp files throw syntax error #62 (comment))
2. Inclusion of the library (*.tpp files throw syntax error #62 (comment))

Problem 1

Looking at the errors, it fails on this line

matio-cpp/test/ExogenousConversionsUnitTest.cpp

Line 60 in e951ef3

VISITABLE_DIRECT_INIT(array_3f, array, {1.0, 2.0, 3.0});

In this case array is supposed to be the name of the field whose type is array_3f. The fact that it throws an error there, it could be related to the version of visit_struct and the availability of the macro VISITABLE_DIRECT_INIT. Please, let us know if the tests also compile fine when unticking USE_SYSTEM_visit_struct

Problem 2

In order to use the library, you don't need to include the folders manually. You would need to use cmake. In particular, you can follow the Inclusion section of the README.

First, you need to install matio-cpp defining a CMAKE_INSTALL_PREFIX, let's say C:\my_folder\my_install (please do not copy and paste this path). Then, you need to add C:\my_folder\my_install\bin (note that I added \bin) to the PATH env variable, and append C:\my_folder\my_install to the CMAKE_PREFIX_PATH env variable (or create that variable if it does not exists already).

Then, you need to add the following lines to your CMakeLists

find_package(matioCpp REQUIRED)

# definition of yourTarget ...

target_link_libraries(yourTarget PRIVATE matioCpp::matioCpp)

[S-Dafarra]

Regarding problem 1, I have tried on my system (running Ubuntu), with the master version of visit_struct, but I haven't found any issue. Hence, the remaining possible cases are:

• VS2017 is not supported (as @traversaro suggested)
• your system version of visit_struct is old

[traversaro]

your system version of visit_struct is old

This may be a good lead indeed. vcpkg has a version of visit_struct that does not contain the features necessary by matio-cpp (see cbeck88/visit_struct#25 and conda-forge/visit_struct-feedstock#1).

[S-Dafarra]

Hi @Chasikanaft, is the problem solved?

[Chasikanaft]

Hi @Chasikanaft, is the problem solved?

Hello, thanks for reply :)
While i took a break in this matter, couse i temporarily decided trough my own visit struct - matio shell.
About visit struct version, now i have 1.0.0 like that repo last tag - https://github.com/cbeck88/visit_struct.

I will try to return to this task soon with an updated VS from 2017 to 2022. Really not sure if that would work, that be weird.

[traversaro]

About visit struct version, now i have 1.0.0 like that repo last tag - https://github.com/cbeck88/visit_struct.

That would not be enough unfortuantly, if I remember correctly matio-cpp uses some features that are not releases in 1.0.0 .
