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

Paul Colby

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.

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?

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 .
