First of all, why do you want to create a hex file? The 'native' format for executable is .axf. The debugger can load this straight into the target board, and the flash programmer can do the same.

If you are really sure that you want a hex files, read this knowledgebase article:

I'm guessing you're hoping to program via Flash Magic.

You'll want to use obj-copy to convert your output files, however you'll also need to ensure that you've properly inserted a CRC into the vector table as per the "Valid User Code" requirements of the LPC (see the user manual).

This can be done with post build actions

[COLOR=black][FONT=Arial]ELF=>BIN without CRC:[/FONT][/COLOR]
[COLOR=black][FONT=Arial]arm-none-eabi-objcopy -O binary ${BuildArtifactFileName} ${BuildArtifactFileBaseName}.bin;

BIN=>BIN with CRC [/FONT][/COLOR](this is useful for USB ISP mode with LPC13xx parts)[COLOR=black][FONT=Arial]:
checksum -v ${BuildArtifactFileBaseName}.bin;

BIN with CRC => HEX with CRC[/FONT][/COLOR][COLOR=black][FONT=Arial]:
arm-none-eabi-objcopy -I binary ${BuildArtifactFileBaseName}.bin -O ihex ${BuildArtifactFileBaseName}.hex[/FONT][/COLOR]

Did you read the link in CodeRedSupport post?
LPCXpresso is for Windows. The post from Jesse.Rosenberg is giving you a lot of information on how to create your hex file.

In the link from CodeRedSupport post, it gives you a way to create your hex file automatically when you build your project.

What details do you need to generate your hex file?

That's an old post (made > 6 years ago) for LPCXpresso IDE v3. The current LPCXpresso FAQs (for IDE v8) are at:

https://community.nxp.com/community/lpcxpresso-ide/lpcxpresso-ide-faqs

And creating hex files is covered in:

Generating srec, binary and ihex files
