Include<boost/lexicast.hpp> no such file directory ::issue

[QT_QT_QT]

Hey guys, I m working on with Boost and I have few problem that I have no clues how to solve it.
I already build the Boost library, following this guideline. And also modify the pro.file according to the guideline, something like this:

***testing Crow.pro***

QT += core
QT -= gui

CONFIG += c++11

TARGET = TestingCrow
CONFIG += console
CONFIG -= app_bundle

TEMPLATE = app

INCLUDEPATH += C:/Users/USER/Desktop/boost_1_60_0

LIBS += C:/boost_lib/boost/bin.v2/libs/date_time/build/gcc-mingw-4.8.1/release/link-static/threading-multi/libboost_date_time-mgw48-mt-1_60.a



SOURCES += main.cpp

HEADERS += \
    crow.h \
    settings.h \
    logging.h \
    routing.h \
    http_request.h \
    utility.h \
    middleware_context.h \
    http_server.h \
    common.h \
    http_response.h \

by right , it should be working now. Some one here have experience include a Boost library in QT Creator? Your help will be appreciated! thanks!

Hi @QT_QT_QT,

Include<boost/lexicast.hpp>

Not sure if its just a typo in your post's subject line, but it's supposed to be boost/lexical_cast.hpp (on Boost 1.58 at least).

Cheers.

@Paul-Colby

yes. Its a typo! Its typo when i copy and paste the code from IDE to this forum. My apologies . Btw, any clue on how to solve this problem?

[Paul Colby]

Thought that might be the case :)

Have a look in C:/Users/USER/Desktop/boost_1_60_0 - do you see a boost directory there, containing a lexical_cast.hpp file? If not, search that directory for the file... I would expect it would actually be under something like C:/Users/USER/Desktop/boost_1_60_0/include, in which case correct your INCLUDEPATH accordingly.

If the file is there, then show us the compiler command and output.

Cheers.

@Paul-Colby

Thank you for the reply, i have tested the solution that you suggested. However it did not work me :(
lexicast is located in the boost folder

at first my modification is like this :
INCLUDEPATH += C:/Users/USER/Desktop/boost_1_60_0/boost/

and then i thought must be the slashed, no need to include a slash at the end of the DIR . something like this:

INCLUDEPATH += C:/Users/USER/Desktop/boost_1_60_0/boost

both of the solutions is not working .

[Paul Colby]

do you see a boost directory there, containing a lexical_cast.hpp file?

Did you find the lexical_cast.hpp file? And if so, what was the full path to it?

[QT_QT_QT]

@Paul-Colby

yeah, i saw lexical_cast.hpp inside folder boost . the full path is C:\Users\USER\Desktop\boost_1_60_0\boost

thanks

Ok, so with:

INCLUDEPATH += C:/Users/USER/Desktop/boost_1_60_0

Show us the compiler command and output (ie the contents of the "Compiler Output" pane, if using Qt Creator).

Cheers.

@Paul-Colby

ok, So far i only got this error which is C1083: Cannot open such file :boost/lexical_cast.hpp':no such file or directory

[Paul Colby]

Without seeing the compiler command being executed, it will be difficult to suggest what might be going wrong. Are you able to show us the compiler command?

[QT_QT_QT]

@Paul-Colby

hi , what is that compiler command ? you want to know the command of building Boost this libraries?

[Paul Colby]

@QT_QT_QT said:

No, I mean the command that results in the "C1083: Cannot open such file :boost/lexical_cast.hpp':no such file or directory" error. Given that you're on Windows (and that the C1083 code is Microsoft's compiler-specific), it will probably start with cl.exe or full\path\to\cl.exe.

If you're using Qt Creator, it should be in the Compiler Output pane, one to several lines before the error message.

[QT_QT_QT]

So, instead of this code C:/Users/USER/Desktop/boost_1_60_0/boots

i changed the code into something like this : C:\Users\USER\Desktop\boost_1_60_0\boost

After the modification , i got an error like this : C1902 :Program Database manager mismatch;please check your installation

[Paul Colby]

The compiler command will look something like:

	cl -c -nologo -Zc:wchar_t -FS -Zc:strictStrings -Zc:throwingNew -O2 -MD -W3 -w34100 -w34189 -w44996 -w44456 -w44457 -w44458 -wd4577 /WX -GR -EHsc -DUNICODE -DWIN32 -DWIN64 -DQT_NO_CAST_FROM_ASCII -DQT_NO_CAST_TO_ASCII -DBUILD_USER=appveyor -DQT_NO_DEBUG -DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_XML_LIB -DQT_CORE_LIB -DNDEBUG -I..\..\bipolar\src -I. -I..\..\bipolar\src -I..\..\bipolar\src\os -I..\..\bipolar\src\polar\v2 -I..\..\bipolar\src\protobuf -I..\..\bipolar\src\threads -I..\..\bipolar\src\widgets -I..\..\bipolar\src\widgets\gpx -I..\..\bipolar\src\widgets\hrm -I..\..\bipolar\src\widgets\tcx -I..\..\..\Qt\5.6\msvc2015_64\include -I..\..\..\Qt\5.6\msvc2015_64\include\QtWidgets -I..\..\..\Qt\5.6\msvc2015_64\include\QtGui -I..\..\..\Qt\5.6\msvc2015_64\include\QtANGLE -I..\..\..\Qt\5.6\msvc2015_64\include\QtXml -I..\..\..\Qt\5.6\msvc2015_64\include\QtCore -Irelease\tmp -I..\..\..\Qt\5.6\msvc2015_64\mkspecs\win32-msvc2015 -Forelease\tmp\ @C:\Users\appveyor\AppData\Local\Temp\1\nm6457.tmp

was trying this solution , however its not working . Some one from here please help me .
