boost : No such file or directory

AntGP

Hello,

I'm having issue compiling a code I inherited with no documentation from a simple zip file . I'm having this error erreor : boost/config.hpp: No such file or directory
Working on Qt5.15.2, the library boost i have installed doesn't seem to be found by Qt, even if, and all file needed are present on the boost folder

According to the .pro the path should be desktop ? if ROOTDIR = C:\Users\agp\Desktop\project\, then INCLUDEPATH should be C:\Users\agp\Desktop\boost ? i don't know if i am rigth, i may need help mostly on that part to understand what all of the .pro mean

But boost (from what i'v read online) is not supposed to be on desktop or anywhere close to the project, but on program files. It's possible there is something about headers but i would neither know how to make sure Qt can find them. I really don't know boost so i may not say too many foolishness about it cause i'm very not familiar with it.

.pro :

#DEFINES += NO_GRAPHVIZ

INCLUDEPATH+=$$PWD
#DEPENDPATH += $$PWD
#include($$PWD/config/config.pri)

DESTDIR = $$PWD/bin
ROOTDIR = $$PWD
OBJECTS_DIR = $$ROOTDIR/objects/$$TARGET
INCLUDEPATH +=$$ROOTDIR/../boost/

unix:INCLUDEPATH+=/usr/include/graphviz

CONFIG += c++11

QT       += core widgets gui svg
LIBS += -Wl,--start-group

for(dep, DEPENDENCY_LIBRARIES) {

    LIBS += -L$$ROOTDIR/lib/ -l$${dep}
    PRE_TARGETDEPS += $$ROOTDIR/lib/lib$${dep}.a
}

LIBS += -Wl,--end-group
QMAKE_CXXFLAGS += -Wno-unused-local-typedefs

full compilation error :

C:\Users\agp\Desktop\project\addons\BoostGraphAddOn.h:5: error : boost/config.hpp: No such file or directory
In file included from ..\..\..\controllers\MElementFacade.cpp:33:
..\..\..\..\project/addons/BoostGraphAddOn.h:5:10: fatal error: boost/config.hpp: No such file or directory
 #include <boost/config.hpp>
          ^~~~~~~~~~~~~~~~~~

(the path of the file is desktop/boost/boost/config.hpp)

I really don't know if someone may understand my issue

But if anyone can land me some help i would be very gratfull, even if it's just to scratch the issue and give me some clue on what i am supposed to do to solve the issue

@AntGP said in boost : No such file or directory:

INCLUDEPATH +=$$ROOTDIR/../boost/

If your include path for searching includes a directory ending in boost then a #include <boost/config.hpp> will not find in the include path's boost directory.

(the path of the file is desktop/boost/boost/config.hpp)

Though this confuses me, I guess it could work if you are looking for boost inside boost. Can you temporarily get rid of the boost/boost level, or even rename it, as that is just confusing?

AntGP

i can try it

result : i still have he issue, it did not changed the error
Now the path is C:\Users\agp\Desktop\boost\config.hpp

@AntGP said in boost : No such file or directory:

Now the path is C:\Users\agp\Desktop\boost\config.hpp

Which expands to

INCLUDEPATH +=C:\Users\agp\Desktop\boost\config.hpp/../boost/

how should this even work? You pass a filename, not a directory...

AntGP

@Christian-Ehrlicher No i did not said that the path i gave to the .pro was C:\Users\agp\Desktop\boost\config.hpp

It was the real path i was trying to reach.

To clearly explain what i did, i tried to remove a layer of boost on my file going from C:\Users\agp\Desktop\boost\boost\config.hpp
to C:\Users\agp\Desktop\boost\config.hpp
Sins it didn't worked then tired other combinaisons
Then whit the base boost/boost path to edit the INCLUDEPATH +=$$ROOTDIR/../boost/ to INCLUDEPATH +=$$ROOTDIR/../
It didn't work either

So i tried to combine the two whit C:\Users\agp\Desktop\boost\config.hpp and INCLUDEPATH +=$$ROOTDIR/../, but it also did not worked

@AntGP Please check the build log to see which include paths are passed to the compiler and check these paths to make sure they are correct..

As everyone can guess i'm really a beginner whit all the Qt stuff
But i think thoose are the compilations logs with the path, or at least, it's the only log where i found any mention of boost. They are the last log before the error message that is posted on the original message of this thread.

full compilation error :

C:\Users\agp\Desktop\project\addons\BoostGraphAddOn.h:5: error : boost/config.hpp: No such file or directory

-IC:/Users/agp/Desktop/project/../boost/
if ../ mean the relative parent path, it would mean -IC:/Users/agp/Desktop/boost/
and whit the #include <boost/config.hpp> used i can assume that it is -IC:/Users/agp/Desktop/boost/boost/config.hpp` ?

Christian Ehrlicher

@AntGP said in boost : No such file or directory:

IC:/Users/agp/Desktop/project/../boost/

So are your boost headers located there?

AntGP

C:/Users/agp/Desktop/project/../boost/ mean C:/Users/agp/Desktop/boost/ ? if it's the case then yes
And so i may have broke somthing on the boost part whit all the move of location of the file, some path inside of it are broken now
The issue may have been solved a while ago, but i may have broken the library on the way

I think i will take some time to restart everything from the begining to be sure i did not miss any step, and that while trying thing nothing have been broke

AntGP

After redoing the entier thing to install boost and using the project straigth out of the zip file, the issue appear to be that I build the library on the wrong place, then moved it at the rigth place, and then wondering why whit the files at the rigth place it was not working

Sins i have to add the path of the library to windows environment variables, moving the library borke everything
And the fact is that don't even have to move the entier library but i can just move a copy of the headers and windows will do the work by itself to link them to the rigth place

This thread at least allowed me to to understand how are build the .pro files, and eliminate the possibility that the issue was coming from Qt

(A video that helped me a lot : https://www.youtube.com/watch?v=5afpq2TkOHc for anyone having the same issue + the info that you need to run powershell on admin mode)

@AntGP said in boost : No such file or directory:

Sins i have to add the path of the library to windows environment variables

Why? And what windows env variables do you mean? All you need to do is to set the INCLUDEPATH correctly (and LIBS if you also add precompiled libs).

AntGP

idk, i did that on the same configuration as before, and it worked :/
I did not understood why it did not worked (reason why i made this post)
Now i don't understand what i did to make it work
