I'm attempting to use a Bridging header but when I try to run my application I get a swift compiler error, when I remove the bridging header and the header file the app runs.
This is the error message I get:
<unknown>:0: error: generate-pch command failed with exit code 1 (use -v to see invocation)
Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc failed with exit code 1
My app has spaces in it's name and I'm denoting that by adding hyphens instead of spaces. I attempted to remove the space by using a backslash and a space like "${SRCROOT}/Project\ Name/headerFile.h" but I got this error message:
<unknown>:0: error: error opening input file '/Users/apple/Documents/Folder/Project Name/Project\ Name/HeaderFile.h' (No such file or directory)
Any advice or pointers would be greatly appreciated.
I just fixed this by using just spaces instead of hyphens or backslash and spaces. Simple enough.

I've tried passing linker flags in various ways but I get various errors
1. build_flags= -Wl, -Map=mapfile.map
2. build_flags= -Wl, Map=mapfile.map
For 1. I get the error message arm-none-eabi-gcc: error: unrecognized command line option '-Map=mapfile.map'
For 2. I get the linker error message ld.exe: error: 'Map=mapfile.map' not found
Your syntax of passing the build flags is not correct. Here is how to do it:
build_flags = -Wl,-Map,output.map

I used Emacs to compile .sml, and I encounter the error:
stdIn:1.6-1.10 Error: unclosed string
As seen in this screenshot:
Once I use the command use ***(sml file), it failed.
No matter what I write, it always has the same error.
I was trying to get my hands dirty with SLAM and I started with ORB-SLAM2 library.
I have downloaded a TUM sequence and wanted to use ROS for it. So I am following the steps according this page.
In Step 7, part 2, when i run ./build_ros.sh, I get the following error:

I went and checked the g2o folder and there is a file by name config.h.
So why am I still getting the error?
In the CMakeLists.txt in /home/sarvagya/Desktop/Swaayatt/ORB_SLAM2/Examples/ROS/ORB_SLAM2/
Try adding
${PROJECT_SOURCE_DIR}/../../../Thirdparty
to the list of include_directories() at line 44 (it should be at that line if you did not change the file)
Adding this line tells the cmake where to find the g2o/config.h.
From the information, that missing g2o/config.h in jacobian_workspace.h, but when I look into the file, and do not find the include in line 36. Do I miss something, or you change something?
I'm knitting some beamer slides in an RMarkdown script in Rstudio on a Windows 7 PC. The slides are in the directory
C:/me/slides/myslides.Rmd
I have a master bibliography that lives in
C:/me/bib/masterbib.bib
I cannot figure out how to link to the bibliography file from the RMarkdown document. Here's the YAML from my attempt:
---
title: "Slides"
author: "me"
date: "2016-12-20"
bibliography: C:/me/bib/masterbib.bib
biblio-style: "apalike"
output:
beamer_presentation:
citation_package: natbib
---
Here's the error:
! Undefined control sequence.
<write> \string \bibdata {C:\me\bib\masterbib}
l.174 \end{frame}
Error: Failed to compile Slides.tex. See Slides.log for more info.
In addition: Warning message:
running command '"pdflatex" -halt-on-error -interaction=batchmode "Slides.tex"' had status 1
Execution halted
I've tried a couple other ways to specify the directory for masterbib.bib, but none have worked. I would prefer to keep the masterbib.bib file where it is, and not make an extra copy in the C:/me/slides/ directory. Thanks for your help!
Edit
When attempting to pass the following into YAML (quoteed with forward slashes):
bibliography: "C:/LaTeXstuff/BibTexLibrary/BrianBib.bib"
I get a fatal error with log output:

I inherited a project (lucky me!) which relies on a static library. Trying to build the static lib, I get this error:
/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/libtool: -dynamic not specified the following flags are invalid: -ObjC
It is followed by these two lines, which I do understand, but this appears to be a separate problem (missing file.)
/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/libtool: can't locate file for: -lFlurryWithLocation
/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/libtool: file: -lFlurryWithLocation is not an object file (not allowed in a library)
Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/libtool failed with exit code 1
Am I wrong, and it's all related? Will the 1st line error go away if I fix the missing file part?
Either way, what does the -dynamic not specified part of message mean?
Thanks!
Olie, your original hunch was correct. There is no relationship between the two messages. The first message '-dynamic not specified the following flags are invalid: -ObjC' is just a warning. The -objC option is not needed for building a static library.
